CYCLING PERFORMANCE TIPS

The Facebook Project -Training with Luqman
A step by step review for a new cyclist
I frequently get questions on designing personalized training programs. Although all the necessary information can be found on various pages of my website, those of you just getting serious about cycling need a better way to pull it all together and make it relevant for your own goals in riding. When I received the following question on the CPTIPS Facebook page, it seemed like a good time to walk through the process, step by step, to develop (or modify) a personal training program.As I get feedback and comments (send them to me at CPTIPS feedback), I will revise and add to this specific webpage.
The Luqman Project
"My name is Luqman. I am a 16 year old student. I got my road bike in December, 2011. I have been joining group rides occasionally from the end of December until now - about 150 miles total. I think I am doing well but I have not seen any improvement. So the group rides I was joining are quite fast, at least for me although it's only 15 miles, and occasionally 35 miles. I have been dropped a few times but it was not consistent. I felt that I didn't improve anything on cycling, and I really need to have some help from the experience.
I have a very beginner road bike, with carbon forks and aluminum frame, equipped with Shimano 2300 8 speed. As for now, I can't afford things like jersey/short, cyclocomputer, shoes but I have a helmet to get me started. I usually use my normal shorts to cycle.
I live in South-East Asia, the weather here are hot and wet through out the year, the terrains near my place are mostly flat but there are quite a lot of hills if I go further away outside the city. I really need some experienced advice or training plans to help me improve. Even though we couldn't meet, I hope you can be my coach. Thank you."
Although it may seem trite, attitude is a major factor in reaching your personal best on a bike. There will be days that you want to cut short your ride, and others where it seems your goal is quite a distance away. Although there are physical characteristics that are common to elite cyclists, more often it is attitude, coupled with a sound training program, that will make the difference in reaching a personal goal. Persistence counts -- and although twelve weeks of training will get you into good riding shape, it will take years to reach your personal best.
The flip side is that attitude alone will not get you to your goal. Success requires incorporating many of the tips that follow on this page (and elsewhere on the website) into a personal training program - a systematic program based on sound principles of physiology. There will be periods of frustration, but overcoming that frustration is what separates the world class riders from those that are just "very good".
This email tells me that Luqman has the first and most basic requirement to become a better cyclist - the desire to be among the best.
A good mileage base is the foundation of a successful training program, important if you want to avoid the types of injuries that keep one from riding that season. So take it slow at first.
If it is early in the riding season, or you have just decided to get back into riding after a period off the bike, you are probably feeling pretty frisky and the tendency is to push yourself. But the first order of business for the training year is to put some unstressed (no intervals, no sprinting up hills) miles on your bike (and body). It's not that intervals or hills are forbidden - just keep them reasonable and not too hard or too often.
Remember, you're banking foundation miles for the season. The best strategy at this point in the training year is to let how you feel on the bike (perceived exertion) tell you when to add that additional effort. If, at the end of the long ride, you feel you could go out and put in a few more miles - you are probably doing it just right. A good target is a base of 500 miles - and as a rule of thumb, don't increase your total weekly mileage by more than 10% over the prior week as you are getting there.
Q."I'm doing base training of 25 miles. Half of the distance is riding into the headwind, and the other half is with tailwind. So, I managed to maintain good high cadence.. so when I'm riding the other half of 25 miles base training, I'm going fast (I think)... around 19-22 mph.. am I too fast for base miles? Am I doing it wrong? But I felt I can maintain good breathing and high cadence, does that mean it's okay?"
A.Remember, the reason you are riding within the limits of comfort is to minimize the chances of an injury during this early season riding. You will have plenty of opportunities to push your limits once we get into a structured training program. As long as you are feeling good, it is fine. As time goes along, you will naturally get faster and still feel comfortable with the pace. You just don't want you to feel you are pushing it - feeling tired - as this increases the chances of pushing too hard and an injury. So it really doesn't make any difference how fast you are going (in fact you might actually do better if you just put some tape over your speedometer and rode like you felt).
Q. Luke: "Can you please make me a base training schedule with a little bit of pedaling/cadence drills inside it that I could follow, for about 10 weeks (or more/less) to 500 miles? I'm trying my best to get a cyclocomputer with cadence, as I want to have a great technique on pedaling as well as high cadence in cycling."
A.Cadence, or revolutions per minute of the cranks, is a number that deserves a few comments. Keeping a good cadence (I encourage 90 - 100 revolutions per minute) will lessen the force delivered by your thigh muscles to the pedals of your bike through the knee compared to a slower cadence for the same road speed. Thus a higher cadence will decrease the chance of a knee injury. Cadence and power output (work being done by your legs) are two different issues, so even in this training base phase, riding at an easy PACE (lower work output), it is good discipline to work on keeping your cadence in the 90 - 100 RPM range.
An example might help. I have found the calculators at the Analytic Cycling website to very helpful in sorting out questions such as this. Assuming you use the basic assumptions suggested on this webpage, and you only change the cadence,you get the following:
Thus maintaining the same road speed (work output) you will get significantly decreased stress on the leg (and knees) riding at a higher cadence.
- 60 revolutions/minute = 260 units of force on the pedal
- 75 revolutions/minute = 208 units of force on the pedal
- 100 revolutions/minute = 156 units of force on the pedal
It will be tough to focus on cadence without a computer, but you can do it. And once you get use to a faster cadence, you will begin to keep it more naturally without thinking about it. It will require concentration at first - and you may find yourself spinning at 65 or 70 as a more natural rhythm for you. But remember, assuming a set pace, faster cadence = less power to the knee per revolution = less stress on the knee joint, =less chance of injury. And 90 - 100 RPM is your goal. (By the way, Lance Armstrong was known for riding at a high cadence, often 120 - 130, and this set him apart from his peerson the road.)
You've ridden your base miles, and it's time to ramp up the training program. The next step, as we move forward, is to look at the goal you've set for yourself (long distance ride - a century perhaps?, multi-day ride/tour, or competitive event) as well as the types of training rides you will be doing along the way. This analysis will help us develop a rational training plan and a sound nutrition program to support the effort. Our final plan should include:
Two aspects of each ride, length (duration) and intensity, will affect planning.
- the weekly mileage goals
- the best use of intervals
- how you will utilize the basics of nutritional physiology to "eat smart" and minimize the chances of "running out of gas" along the way.
The following 6 examples cover the most common training ride and goal ride scenarios.
- Ride Length/Duration
- Goal ride length will determine total weekly training mileage and the the distribution of mileage across weekday rides
- if any ride will be more than 2 hours (including training rides), you will need to think about oral Caloric supplements.
- Ride Intensity
- if the goal ride involves riding at > 80% VO2max, intervals will be an essential part of your weekly training program
- if you will be riding at > 80% VO2max, and will be on the bike for more than 2 hours, you will definitely need carbohydrate supplements to maintain internal muscle glycogen stores for what may become an intermittently anaerobic effort.
Q. Hi there, currently I'm doing my base miles. I've got my cadence computer already and training 90-110 rpm. But ... I don't have HRM, so how do I know I'm doing the right intensity for base miles?
- THE COMMUTE or SOCIAL RIDE
- Duration - less than 2 hours
- Intensity - 50 - 60% VO2max
This ride is done at a comfortable pace of 50-60% VO2 max. for 1 to 2 hours, often multiple days of the week. The goal is a comfortable ride with energy left for the remainder of the day.
- BASIC TRAINING RIDE (often referred to as LSD or long, slow distance)
- Duration - 2+ hours
- Intensity - 50 to 100% VO2max
- Duration - generally less than 2 hours
- Intensity - 80 to 100% VO2max
- LONG DISTANCE
- Duration - more than 2 hours
- Intensity - 60 to 80% VO2max
- COMPETITIVE EVENT
- Duration - 1 - 4 hours
- Intensity - 80 to 100% VO2max
- MULTI-DAY RIDE or BIKE TOUR
- Duration - multiday, 4 - 6 hours per day
- Intensity - 50 to 80% VO2max
A. There is a two part answer to your question.
First, for this period of time you are putting in your base miles, you should not be worrying about your riding intensity (except to avoid pushing yourself and getting hurt in the process). It is okay to vary your riding, do occasional sprints, but you should not be at a level of focus where a HRM would be needed.
Then when we do get to outlining a training program, and want to track your exertion, I prefer to use perceived effort (exertion) -- often expressed as %VO2max -- rather than a HRM to track a level of exertion.
If you are interested in how your perception correlates with your heart rate (without a HRM) and your %VO2max, you can get a good approximation by
You now have a quick and easy correlation between perceived exertion, HR, and your your personal %VO2max.
- ride at a steady pace for 5 minutes or so
- estimate your level of exertion on a scale of 6 to 20
- then stop your bike and count your HR for 30 seconds.
- double this number and use this calculator
Let's work through a quick example. Your training program calls for a recovery ride at 80% VO2max. This is actually a fairly reasonable pace so you want to be sure you are not pushing your upper limits (which is the challenge of these recovery rides).
This example demonstrates that a target heart rate of 146 (on a HRM), a perceived effort of 15, and 80 %VO2max are all different ways of expressing a single level of exertion.
- First, determine your MHR (maximum heart rate). I prefer the real time approach, on the bike or a trainer, rather than using your age. For purposes of this example, let's say your personal MHR is 165 beats per minute (BPM).
- Using our calculator, 80% VO2max = 88.2% MHR.We now know your target HR (165 x .882) = 146 beats per minute.
- The final step is to get on the bike and do a ride at a pace that you estimate (perceived effort) is about 80% of your maximum. And for the purposes of this example, you should quantify it. You are aiming for a 15 (a number than when multiplied x 10 would equal your heart rate).
- After riding for 30 minutes, stop the bike, count your pulse for 30 seconds, and double it. If it is 145 +or- 5 BPM I think you are right on track.
VI. Training PhysiologyThere are a few key physiologic principles that we will use as we develop a training program that is specific for you. I will highlight them here.
- No pain, no gain. I'm sure you have heard this phrase many times at the gym or on the track. The concept of stress leading to adaptive changes is the rationale behind all training programs.
A focused training program can increase your maximum performance by 15 to 30% over a 3 month period and by up to 50% over 2 years. And the converse is true as well, there is a drop off in performance and metabolic training adaptations within a few weeks of stopping a regular training regimen, although certain adaptive physical changes (such as the number of muscle capillaries and skeletal and cardiac muscle fiber size) probably occur more slowly.
Regular exercise (walking, running, cycling, etc.) stimulates changes in the cardiovascular system, lungs, and muscle cells which improve oxygen delivery and thus work capacity - for both endurance and sprint activities. Oxygen is extracted from air in the lungs and then transported in the blood to the cells where it is extracted and utilized. The byproduct of energy production, carbon dioxide, is then transported back to the lungs by the circulating blood and leaves the body in expired air.
There are also improvements in the efficiency of energy production to support high level performance:
And finally there are changes in the musculoskeletal system, changes in the physical structure within the muscles and ligaments to withstand the stresses of prolonged exertion including strengthening of the connective tissue between muscle fibers to minimize the microtrauma (and post exercise discomfort) that often occur with physical exertion.
- metabolic adaptations to facilitate aerobic energy production from glucose and glycogen
- improvement in lactic acid removal from the muscle cell.
- an increase in lipid metabolism at any level of exertion which results in extra energy Calories from fat to supplement those from glycogen and glucose metabolism at any specified level of activity
These training related adaptations in the CV, metabolic, and musculoskeletal systems will allow you to perform at a higher level for longer periods of time.
- VO2max or Maximal Oxygen Consumption is defined as the maximum amount of oxygen that an exercising individual can utilize in a predefined period of time (generally expressed as a volume i.e. liters per min). It can also be normalized per kilogram of body weight (i.e. ml per kg BW per min). It is a measurement reflecting the upper limit of aerobic muscle cell metabolism and is a product of the maximal cardiac output (amount of blood being circulated per minute by the heart)AND the maximal arterial-venous oxygen difference at the muscle or tissue level (the amount of oxygen that can be extracted from each ml of blood passing by the cell. It will increase with training,
When we construct a training program, the %VO2max is used as a reflection of the degree of exertion on a ride. Generally you will ride at one of 3 levels.
- 100% VO2max - interval training
- 80% VO2 max - this level does lead to conditioning and improvement of performance, but not as quickly as with intervals
- 50 - 60% VO2max - for recovery days and the longer ride of the week.
- aerobic vs anaerobic metabolism. For the most efficient production of "usable" energy (by the muscles) from the food we eat, oxygen is necessary. Oxygen is extracted by the lungs from the air we breathe and then transported via the cardiovascular system (bound to hemoglobin) to the cells where it will be utilized. One of the end products of energy production, carbon dioxide, is then transported back to the lungs and leaves the body in expired air.
When there is adequate oxygen to support energy production, metabolism is said to be aerobic. When thedemand for energy at the cellular level outstrips the ability of the cardiovascular system to provide adequate oxygen for oxidation, a more inefficient form of metabolism, anaerobic metabolism, comes into play.
Training improves the level of exertion that can be maintained by aerobic metabolism alone. And a structured program that includes "intervals" which stress the muscles into an anaerobic zone, will increase the speed of this improvement.
VII. Two Components of a Successful Training ProgramWe are almost there, designing a training regimen for you.
To be successful in meeting your training goals, you will need two things.
- you have put in your 500 base miles
- you have given thought to your ultimate goal (both ride length/duration and ride intensity/pace)
- we have reviewed the basic physiologic principles common to all training programs
- and you can estimate your level of exertion while riding - from a leisurely pace of a recovery ride at 50% VO2max to an all out anaerobic interval/sprint at 100% VO2max
Failure to adequately replace fluid losses associated with exercise is the single biggest contributor to poor performance in competitive athletes. This is especially true in cycling where evaporative losses are significant (sweating and loss through the lungs can easily exceed 2 quarts per hour).
- First is a traditional weekly program of rides to improve the performance of your cardiovascular and musculoskeletal systems - the engine that drives the wheels of your bike.
- The second, often overlooked, is a nutritional plan that lets you take maximum advantage of your training. Nutrition is the fuel for the work you will do. And you can have the most highly tuned cardiac and respiratory systems in a pack of riders and yet lose the race as you run out of fuel. A sound eating program will not magnify your advantage, but a failure to eat properly will definitely limit the benefits of your training.
To take advantage of your training program, and assure that you perform at your personal best, it is essential that fluid replacement begin early and continue throughout a ride.
A South African study comparing two groups of cyclists (one focusing on staying hydrated, the other not) exercising at 90% of their personal maximums demonstrated a measurable difference in physical performance as early as 15 minutes into the ride.
While riding you should be taking in a minimum of 4 to 5 ounces of fluid every 15 minutes or 1 to 2 standard water bottles per hour. When extreme conditions of heat and humidity are anticipated, and the risks of dehydration are higher, the following strategy of maximizing hydration before you start the activity can be a good preventative measure.
- drink 20 oz of cool water 2 hours before exercise
- 8 to 16 oz 30 minutes before
- and then 4 to 8 oz every 15 minutes on the bike
But a word of caution. With the frequent emphasis on "staying hydrated", the pendulum on fluid replacement requirements can swing to the opposite extreme where overcompensation, drinking excessive amounts of electrolyte free water (read sodium or salt here), has occasionally led to an even more serious and life threatening condition - dilutional hyponatremia (low blood sodium concentration).A recent study found that overhydration with hyponatremia was a far more frequent finding in runners who had collapsed than dehydration.
Here are several hydration tips:
We will cover the components of a traditional training program next, and then move on to optimizing your nutrition.
- Hydrate before, during, and after the ride - force yourself to drink as thirst alone will not reflect complete rehydration, so learn to drink before you are thirsty. Using a CamelBak or similar device on long rides will eliminate worries about stopping and possibly losing your group. Watch the color of your urine, if you are doing a good job on replacement it should be colorless.
- Don't skimp when using a sports drink - don't assume that because they contain electrolytes and carbohydrates you don't need to drink as much. As the sweet taste often keeps you from drinking, dilute it or take an extra bottle of plain water to alternate.
- Keeping liquids cool has been shown to increase intake on a ride - either add ice the day of the ride or freeze half a water bottle of fluid the night before and top it off with water from the tap or extra sports drink just before the ride.
- Weigh yourself before and after the ride - most of your weight loss will be fluid (2 pounds equals 1 quart or "a pint's a pound"). A drop of a pound or two won't impair performance, but any more and you need to reassess your personal hydration program. A gain of more than 1 or 2 pounds suggests you are over compensating. This is an especially important strategy in hot weather where fluid losses can easily exceed several quarts an hour.
- Wear the right clothing - light colored to reflect heat and a loose weave jersey to help keep you cool and lessen sweat losses.
- Wear your helmet - modern well vented helmets funnel the wind onto your head and are actually cooler than your bare head. And the helmet material will insulate your head from the heat of the sun's rays.
IX. Your Training ScheduleNow that we have covered basic training principles, we will pull them together into a rational training program for you. The basic unit of our training program will be the training week. Seven days of riding and resting.
Each day on the bike has two components - ride length/duration and ride intensity, the same two aspects I asked you to consider in defining your season's riding goals above.
Each week will consist of 5 days on the bike - 1 high mileage day, 1 slow recovery day, and 3 intermediate mileage days of variable intensity. The other 2 days will be rest days - off the bike (or short recovery rides).
We'll cover the details (length, intensity) of each ride, and how they fit together into a training week, in the next several sections. But first, a few comments on "rest". One of the bigger risk an enthusiastic rider faces is overtraining,right after pushing too many miles and developing a physical injury (the reason one has to be disciplined and put in those base miles before starting to push oneself.
Fatigue, the tiredness one feels after riding, is a normal part of the training process. It is to be expected after the physiologic over load of exercise and is a natural response to the stimulus which leads to adaptation and performance improvement. Fatigue is our signal that we are pushing our physical limits. However, in certain circumstances, fatigue can be a warning that we are pushing too hard (that there is an imbalance between exercise and recovery), and indicate the need to back off or risk an actual deterioration in our performance. This is a common dilemma in a personal training program: Hard work makes us faster, but how much is too much?
One of 5 types of fatigue, overtraining is the result of " doing too much, too quickly". The body responds well to regular, moderate changes, not upheaval, in a training program. So the rationale for rest days, recovery days on the bike, and limiting mileage increases to no more than 10% per week, is to minimize the risk of overtraining and the debilitating and often long term (weeks to months) fatigue which limits rather than stimulates improvement in performance.
The most important aspect of preventing overtraining is realizing you are almost there. A good training diary is a tool you can use to alert yourself to this risk. In addition to the usual training facts such as mileage and times, it should include a daily notation on:
Next, more about the 3 types of training rides - high mileage days, slow recovery days, and the intermediate mileage days of variable intensity.
- resting heart rate before getting out of bed
- mood self assessment
- self assessment of level of fatigue throughout the prior day ("heavy legs")
- minor illnesses - i.e. GI upset, diarrhea, sore throat, and runny nose
- performance (time) on a weekly standardized ride done at your perceived maximum. More scientific would be measurement of oxygen consumption (down), heart rate (up), and blood lactate levels (down).
X. Your Training WeekFirst step, calculate your average weekly mileage for your last 2 or 3 weeks of riding. This will give you the mileage of your first week - then, to minimize injuries, you should increase your weekly mileage by no more than 10 to 15% per week. Here is an example of the process - Example.
You can also estimate the length of a training program to reach a personal goal by using the average long ride from your 500 mile base training period, increasing it by 10 - 15% a week, and repeating this until you arrive at a figure that is equal to or greater than 75% (3/4) of the length of the event for which you are training. The number of repetitions needed to get to the 75 % number is the number of weeks of your training program. See Step 2 in the example.
How should your mileage be divided throughout the week? It will require balancing frequency, intensity, and duration of the individual rides to achieve your personal goal. For more detail, review this summary of training techniques. Here is how I balance the three.
It's important to ride at least 5 days a week, and take at least one day off.
Be flexible and adjust your program to your lifestyle. A rigid program is destined to fail.
- One high mileage day - working up your mileage by 10 to 15% per week until it equals your event distance
- The longest mileage day is keyed to the length of your event or ride and ridden at the pace you hope to maintain for the event. Many coaches suggest you work up to the length (or even 125% of the length) of the event while others are comfortable if you can ride 75% of the event distance comfortably.
- This is usually a Saturday ride, with Sunday as a backup for bad weather or other unexpected circumstance that might derail your training program.
- The last high mileage day of your training program should be at least 75% of the length of the planned event.
- If you are training for a single day event or ride, your longest training ride should be at least 10 to 14 days before the event. Cut back on the mileage of your rides 3 days before the event, substituting short, low intensity rides (spinning) to keep your muscles from tightening up. This recommendation is not as important for multiday endurance type rides, but common sense suggests that taking a few days off (short spinning rides only) immediately before an event will facilitate maximum muscle recovery and glycogen repletion.
- Follow the high mileage day with a rest day (or if you prefer, a 6th riding day - at most 1/4 of the length of your long ride and ridden at a leisurely pace to help loosen up your muscles after the long ride of the week).
- Three intermediate mileage days
- The three intermediate mileage (midway between the short ride and the long ride of the week) days should be ridden at a good training pace (85 to 90% of your maximum heart rate). At least one should be an interval training ride. A second interval training day each week is optional.
- One slow recovery day - longer than the intermediate mileage days, shorter than the high mileage day.
- One or two rest days - off the bike or short recovery rides. Depending on your level of training (or evidence of overtraining) the seventh day is an additional intermediate mileage day or an additional rest day.
As far as pace of your rides:
- the pace of the longest ride of the week should match the planned pace of your event
- the short "recovery" ride should be a leisurely pace at no more than 50-60% of your maximum heart rate
- two of the intermediate rides should be at the planned event pace
- one of the intermediate rides (preferably prior to a planned day off the bike for a 5 day training week), should be at a brisk pace 2 - 3 mph faster than your planned event speed.
XI. Nutrition BasicsYou may have the best training program in the world and have developed the optimum "engine" for your cycling event, but if you don't eat right, that is provide the optimum "fuel", you will not ride at your best.
How should one eat to get the most out of their training program? There is a two part answer.
- First, which type of Calorie (carbohydrate, fat, or protein) is best to support the exercising muscle?
- Second, what are the effects of exercise on the digestive tract, important in deciding what and when you should eat to get those Calories into your system.
I. Type of Calorie - carbohydrate, fat, or protein
Carbohydrates which contain 4.1 Calories per gram (120 Calories per ounce) are the preferred fuel for muscle metabolism.
Fats contain 9 Cal/gram.
- Carbohydrates are stored as glycogen in the liver and muscle cells - your body contains about 1500 Calories of glycogen (enough for 2 hours of exercise if you eat nothing at all)
- The carbohydrates you eat are either simple 6 carbon sugars such as glucose or complex (composed of multiple 6 carbon units). Complex carbs are digested and enter the circulatory system more slowly.
- Caloric value of CHO depends to a degree on whether one is exercising aerobically or anaerobically. This is where the concept of VO2 max comes in. Above 100%VO2 max, you no longer have enough oxygen to support efficient use of food energy. For example, carbohydrate metabolism will produce 19 times as much energy per gram when carbohydrates are metabolized in the presence of adequate cell oxygen supplies (aerobic) as opposed to its metabolism in an oxygen deficient (anaerobic) environment.
Protein is only used as an energy source in malnourished states.
- The disadvantage of fat as a fuel for exercise is the fact that fat is metabolized through pathways that differ from carbohydrates and alone can support an exercise level approximately 50% VO2 max. at most. As performance levels increase, the percentage of Calories provided by fat decreases.
- Even the leanest athlete has plenty of stored fat available (approximately 100,000 Calories worth in a 70 kg male)
- They play only a minor role in short distance, maximum performance events at 90 to 100% VO2 max.
- Fat Calories are fine for lower work intensity which makes fat the ideal fuel for endurance events. They are a particularly important energy source for the endurance cyclist.
(see NUTRITION FOR TRAINING AND PERFORMANCE for a more detailed discussion).
When the body's 1500 stored carbohydrate Calories are gone, only fats are left (plus any carbs you eat) At that point, the exercise level drops to 50% VO2 max. at most as there is only fat to provide your exercise Calories. One can avoid the bonk by:
- supplementing stored carbohydrates with eaten carbohydrates
- exercising at lower levels of exertion (lower VO2) where less CHO is being used to provide Calories for exercise. Thus slowing the pace increases the % of energy derived from fat and can extend carbohydrate reserves.
II. Effects of exercise on digestion (getting what you eat into your system and to the muscles).
Before we go any further, let's take a minute to discuss the role of the various parts of your digestive tract.
- Mouth - important to begin the mechanical breakdown of food and add some digestive enzymes in saliva
- Esophagus - transportation to the stomach
- Stomach - further mechanical and enzyme breakdown; no absorption
- Small intestine - completes enzyme breakdown and absorption into the blood with transport to the muscle cell
- Colon - storage and dehydration of already processed food; no absorption
When designing a nutritional program to supplement your body's 1500 stored Calories for an athletic event, the rate of digestion and absorption of foods must be taken into account. The time needed for:
will directly affect how quickly any food will be available to the muscle to provide the supplemental Calories for exercise.
- the stomach to start the digestive process
- empty its contents into the small intestine
- and have the food components absorbed into the bloodstream
Emptying of the stomach into the small intestine is the rate limiting step in getting Calories into the blood stream and to the working muscles. Once food molecules get into the small intestine, they are absorbed quite quickly. You have control over the four major factors that can delay stomach emptying.
- Solid versus liquid - liquids are emptied from the stomach more quickly than solids.
- Fat content of the food - fat slows the digestive process and delays the availability of any Calories in the food to the muscles.
- Sugar concentration - especially in liquids, a sugar content of more than 10% will slow stomach emptying. ( The use of complex carbohydrates, due to the decreased osmotic effect, will offset this to some degree and offers an alternative strategy to maximize Caloric intake to offset the metabolic needs of exercise.)
- Physical activity level of the cyclist - the mechanical activity of digestion is slowed by any vigorous activity, usually starting at 70% VO2 max. Except in short, all out events, this is rarely an issue, and it is much less so for cycling than for running where the additional component of mechanical stimulation of abdominal contents from the sport itself slows digestive tract functioning.
The bottom line? The optimal food for a rapid, high-energy boost during a ride would be a semi-liquid or liquid carbohydrate with minimal if any fat. On the other hand, an endurance athlete, competing at a lower VO2 max., might prefer a complex carbohydrate with some fat added to improve taste (and generally in a solid form), in order to slow emptying from the stomach and even out absorption over a longer period of time.
This page summarizes the key nutrition concepts that you should incorporate into your personal nutrition program.
XII. Scheduling Your Calories - The rule of 4'sNow that we've briefly covered key nutrition basics and the importance of carbohydrates in fueling your bicycling effort, let's spend a minute looking at the timing of your intake. After that we will pull it all together in specific eating and nutritional guidelines for the various types of rides discussed in Section IV above.
There are several principles that underpin what I am going to call "The Rule of 4's" - my suggestions for timing your nutrition. They are:
The next section will apply these principles to emphasize critical times to consider in planning your eating program to maximize your physical performance - the Rule of 4's:
- There is overwhelming evidence that adequate dietary carbohydrates are needed for maximum performance.
- There is NO evidence that more than 2 grams per kg per day of protein are beneficial in endurance, sprint, or power training/performance.
- There is no evidence that dietary fat has any role in single day, high performance (%VO2max greater than 60%) activities.
- The body's normal liver and muscle glycogen will support the first 1 or 2 hours of exercise at 70% VO2 max. without any need for supplementation.
- Taking in carbohydrates during the event provides an additional source of glucose "fuel" that will extend the length of time before the bonk occurs.
- Eating a high carbohydrate diet for several days prior to an event will maximize your internal glucose (glycogen) stores, and will prolong the duration of activity until fatigue occurs.
- 4 days prior (to the event)
- 4 hours prior
- 4 minutes before

XIII. Applying The Rule of 4's to 6 Types of RidesWe have previously stressed the importance of clarifying your goals to let us tailor a riding schedule for your physical training. The same logic applies to developing your "nutritional program". As I emphasized previously, nutrition is the fuel for your bicycling engine - and just as you would not put regular gas in a high performance sports car, poor eating will lead to suboptimal performance on the bike.
To review, your ride will generally fall into (or close to) one of 6 classic types:
- Commute or Social Ride - mild to moderate effort, 15 to 20 miles
- Basic Training Ride - moderate intensity, 15 to 50 miles
- Intervals - intermittently high intensity, 10 to 30 miles
- Long Distance Ride - moderate intensity, 50 to 100 + miles
- Competitive Event - high intensity, 20 - 30 miles
- Multiday Ride - moderate intensity, 50 to 100 miles per day
Each ride has its own challenges:
More details can be found on my webpage Nutrition Plans For 6 Common Types of Rides. I also took a stab at putting this in a matrix format to allow easier comparison of nutritional plans.
- If the ride is going to be longer than 30 or 40 miles, especially if it is a multiday ride, a high CHO diet in the prior 3 days is helpful. You want to maximize your internal glycogen stores
- If the ride is going to be high intensity, you don't want to eat in the 4 hours before the event to minimize gastric upset.
- If the ride will be more than 2 hours, it is important to eat (snack) while riding or deal with an increased chance of the bonk.
- For multiple day rides, or if you are riding daily in a structured training program, it is very important to take advantage of the post ride window where the muscles preferentially restock glycogen stores so that you are prepared for the next day.
XIV. RecoveryAsk a cyclist about their personal training program and you can talk for hours about mileage, intervals, and nutritional secrets. But you won't often hear about an equally important 3rd pillar of a successful training program - recovery. (The 1st and 2nd are cardiovascular training and nutrition.) Although recovery is often considered the last task of the current training day, it is the bridge that prepares you for your next riding day.
Replenishing muscle and liver glycogen stores is the most important focus of the post ride recovery period, but fluid replacement and rest need a few comments as well.
- NUTRITION- The emphasis here is carbohydrates - the fuel you used to power your ride. As you replace those carbohydrates, you will want to take advantage of a 4 hour window that immediately follows vigorous exercise. During these interval, any carbohydrates ingested are converted into muscle glycogen at 3 times the normal rate. Studies suggest this window quickly closes with a 50% decrease in the "super charged" repletion rate by 2 hours before returning to the normal carbohydrate repletion rate of 5% per hour 4 hours post exercise. You can review the particulars on post ride carbohydrate replacement at this link.
Although it may require up to 48 hours for complete muscle glycogen replacement following the depletion associated with a 2 hour ride, for all practical purposes glycogen stores are almost completely restored in the first 24 hours post event. If that is the case, why worry a bout the 4 hour window? For an athlete who is on a daily training schedule, or is involvedin a multiday event, it provides a strategy to get a jump on the normal repletion process, minimizing the chance of slipping into a state of chronic glycogen depletion (and the fatigue that goes along with it).
How much glucose is enough during this 4 hour interval? Most studies have suggested that you can incorporate up to 3 grams of carbohydrate per kg of body weight during the 4 hours, and up to 10 grams per kg over the post ride 24 hour period. My suggestion would be to spread the 3 grams/kg BW of carbohydrate over the entire four hours after exercise at a maximum rate of 1.0 gm of carbohydrate per kg body weight per hour. At 4 Calories per gram, this would be approximately 300 Calories per hour for the average rider. This is equal to a couple cans of soda when you get off the bike and then some healthy snacks before an early lunch or dinner.
- FLUIDS- One of the most common mistakes of competitive athletes is failing to replace fluid losses. This is a particular risk in cycling as rapid skin evaporation decreases the sense of perspiring. As maintaining plasma volume will optimize your physical performance, make it a point to weigh yourself before and after the ride - any weight loss will be fluid, and 2 pounds is equal to 1 quart of water. A drop of a pound or two won't impair performance, but a greater drop indicates the need to reassess your drinking regimen on the bike. And if you find you have guessed wrong on replacement needs, you can use the post ride period to begin replacement of any excess losses.
- REST- Overtraining is a risk in any training regimen, so take a minute as part of your recovery program to ask yourself after every ride if your level of fatigue is more than you expected. To review, a cyclist may experience 4 distinct types of fatigue:
Although it may seem paradoxical, structured rest is a key component of all training programs and may actually be one of the toughest training choices you'll have to make. To minimize the risk of overtraining, you should include at least one and occasionally two rest days per week along with a day of easy spinning.
- The bonk (fatigue resulting from muscle glycogen depletion) usually develops 1 to 2 hours into a ride. It is a particular problem if "on the bike" glucose supplements are not used to extend internal muscle glycogen stores.
- Post ride fatigue is a normal response to several hours of vigorous exercise and indicates we are pushing our training limits. It leads to improved performance the next time out.
- Over reaching is the next step up - the fatigue we feel at the end of a particularly hard week of riding. It is really just an extension of #2, and will, with recovery, make us faster and stronger.
- Overtraining is the debilitating and often long term (lasting weeks to months) fatigue which limits rather than stimulates improvement in performance.
Over reaching is a normal part of the training cycle. It may require several extra (and unplanned) recovery days. But if you find that your performance is not improving with several extra recovery days, it's time to take a break from riding and switch to alternative aerobic activities (at 70% maximum heart rate to maintain your cardiovascular fitness). To push ahead is to risk a level of overtraining which may require a month or two off the bike to recover.
XV. Training Pitfalls and MisperceptionsThe above sections cover the components of a well rounded training program. Now I would like to look at the practical challenges of pulling them together into your personalized training program. To do so, I am going to use excerpts from a number of questions sent to me.
Taking them one at a time should help clarify comments I have made - or where I place my emphasis in applying training concepts. As we go along, feel free to send me your questions and I will try to answer them for you. I promise to keep any excerpts anonymous. Send them directly to me at firstname.lastname@example.org
- Be clear in your goal.
- "My goal is to be an all-rounder cyclist. I want to be able to ride flats, climb, sprint, time trial, and descend."
- Having a clear goal is key in designing an appropriate training program. Even though we all would like to be that ideal, all around rider, it is the rare rider that can excel in all aspects of the sport. That means to be successful, you need to be very specific as to your goal. As you train, and ride, you will have a better ideas as where you do excel - and may decide to change your goal to increase your chances of success. Or you can be more scientific about it. However you get there, your personal goal will help plan the mix of training rides as well as your nutritional support program. So, hard as it may be, pick one - riding flats OR climbing OR sprinting...you can see what I mean.
- Getting better - it's not just about the miles
- "I can only bike 4 days a week. Some suggestion only: one long distance ride, I'm able to find a route 50km or more(doing a loop twice), a fast group ride, an interval day (what interval - please be specific), climbing & descending (hill repeats), other you decide."
- I am going to assume that by improvement you mean getting faster for your weekly group ride. Just putting on miles will get your body in shape for longer times on the bike, but to improve your speed and get faster for a set distance, you need to stress your cardiovascular system - and that means intervals.
You definitely need at least 1 interval day a week. My preference is to use fartleks as they give me more flexibility while riding and are more interesting to my style (less boring). But you will need to push 5 or 6 set intervals of distance on that day, once a week, to improve. If you are already well trained and want to add that edge for the last few weeks before a competition, take a look at High Intensity Training, a specific form of intervals.
- Improving on the hills - no pain, no gain
- " I have noticed that on some of the hills that I ride that take about 15 minutes to complete in March, I am riding up them in about the same amount of time or longer now after riding all season. I feel faster, but the times don't show it. Is that normal to not go faster up hill later in the season?"
I in turn asked: Tell me a little about your riding season - and training. Did you do any interval work - or a regular training ride that focused on hill climbing? I'm interested in whether and how you pushed yourself.
"I haven't done any specific interval training. I spend about 1/2 of my time on the road and 1/2 of my time on the mountain bike. During the spring I ride about 3 days a week and during the summer since I am off from work, I ride about 5 days a week. I ride using my heart rate monitor most of the time and use it to make sure on easy days I am going easy. On days that I feel good, I just ride and not look at the heart rate. Most of my "interval work" is done on the group ride or on the mountain bike. On the mountain bike there is no set intervals, just riding fast on the trails. On the group rides the pace just goes up, so the effort goes up."
- My comment: Although putting in the miles will get your body in shape for longer rides on the bike, I doubt you will improve on your ability to generate watts of power at the rear wheel (the power that moves you on the bike and determines how fast you ride on the flats or up hills) without incorporating intervals into a day or two or your training week. Add intervals next year (maybe do them as attempts to sprint up a small hill) once or twice a week which is a form of interval training, and I bet you will be pleasantly surprised.
