There are obviously more than ten mistakes that an athlete can make—and in this latest incarnation of this article, you’ll notice I’ve included an “honorable mention”— but those listed represent the most common performance-ruining gaffes.
As you read through each of these mistakes, at least some of them will sound painfully familiar. However, we just don’t tell you what you’re doing wrong; each of the ten sections also provides the appropriate corrective action. Follow this advice and you’ll quickly see significant improvement in your overall performance.
Optimum nutritional support for endurance athletics means consuming the right amount of the right nutrients at the right time. You can neither overload nor undersupply your body without compromising athletic performance and incurring detrimental results. The principle of avoiding both too much and too little especially applies to hydration, where serious consequences occur from either mistake. If you don’t drink enough, you’ll suffer from unpleasant and performance-ruining dehydration. Drink too much, however, and you’ll not only end up with impaired athletic performance, you may even be flirting with potentially lifethreatening water intoxication.
One of the most respected researchers on hydration, Dr. Tim Noakes, studied the effects of thousands of endurance athletes and noted that the front-runners typically tend to dehydrate, while overhydration occurs most often among middle to back-of-the-pack athletes. Both conditions lead to hyponatremia (low blood sodium), but through different processes. Excess water consumption causes what is known as dilutional hyponatremia, or an overly diluted level of sodium and electrolytes in the blood. This is as bad as underhydrating in regards to increased potential for muscular cramping, but has the added disadvantages of stomach discomfort, bloating, and extra urine output. And, as mentioned earlier, in some unfortunate circumstances, excess hydration can lead to severe physiological circumstances, including death.
Unfortunately, endurance athletes too often adopt the if a little is good, a lot is better approach. This can lead to significant problems when you’re trying to meet your hydration requirements. All it takes is one poor performance or DNF due to cramping and you start thinking, Hmm, maybe I didn’t drink enough. Next thing you know, you’re drinking so much water and fluids that your thirst is quenched but your belly is sloshing and you’re still cramping. Remember, both undersupply and oversupply of fluid will get you in trouble.
How much should one drink? One expert, Dr. Ian Rogers, suggests that between 500-750 milliliters/ hr (about 17-25 fluid ounces/ hr) will fulfill most athletes’ hydration requirements under most conditions. I believe all athletes would benefit from what Dr. Rogers says: Like most things in life, balance is the key and the balance is likely to be at a fluid intake not much above 500 milliliters (about 17 ounces) per hour in most situations, unless predicted losses are very substantial.
[Rogers, I.R. Fluid and Electrolyte Balance and Endurance Exercise: What can we learn from recent research?, Wilderness Medicine Letter, 18:3, USA (2001)]
We at Hammer Nutrition have found that most athletes do very well under most conditions with a fluid intake of 20-25 ounces (approx 590-740 milliliters) per hour. Sometimes you may not need that much fluid16-18 ounces (approx 473-532 ml) per hour may be quite acceptable. Sometimes you might need somewhat more, perhaps up to 28 ounces (approx 830 ml) hourly. Our position, however, is that the risk of dilutional hyponatremia increases substantially when an athlete repeatedly consumes more than 30 fluid ounces (nearly 890 ml) per hour. If more fluid intake is necessary (under very hot conditions, for example) proceed cautiously and remember to increase electrolyte intake as well to match your increased fluid intake. You can easily accomplish this by consuming a few additional Endurolytes capsules, or adding more scoops of Endurolytes Powder or Endurolytes Fizz tablets to your water/fuel bottle(s).
We believe that fructose, sucrose, glucose, and other simple sugars (mono- and disaccharides) are poor carbohydrate sources for fueling your body during exercise. Also, for optimal general health you should restrict your intake of these simple sugars (see the article 146 Reasons Sugar Ruins Your Health).
For endurance athletes, the primary problem with fuels containing simple sugars is that they must be mixed in weak 6-8% solutions in order to match body fluid osmolality parameters (280-303 mOsm) and thus be digested with any efficiency. Unfortunately, solutions mixed and consumed at this concentration only provide, at the most, about 100 calories per hour, inadequate for maintaining energy production on an hourly basis for most athletes. Using a 6-8% solution to obtain adequate calories means your fluid intake becomes so high that it causes discomfort and bloating, and you may possibly overhydrate to the point of fluid intoxication.
You can’t make a double or triple strength mixture from a simple sugar-based carbohydrate fuel in the hopes of obtaining adequate calories because the concentration of that mixture, now far beyond the 6-8% mark, will remain in your stomach until sufficiently diluted, which may cause substantial stomach distress. You can drink more fluids in the hopes of self diluting the overly concentrated mixture, but remember that you’ll increase the risk of overhydration. However, if you don’t dilute with more water and electrolytes, your body will recruit these from other areas that critically need them and divert them to the digestive system to deal with the concentrated simple sugar mix. This can result in a variety of stomach-related distresses, not to mention increased cramping potential.
The bottom line is that simple sugar-based drinks or gels have to be mixed and consumed at very dilute and calorically weak concentrations in order to be digested with any efficiency. A simple sugar-based product used at a properly mixed concentration cannot provide adequate calories to sustain energy production. Any way you look at it, fuels containing simple sugars are inefficient and therefore not recommended during prolonged exercise.
Complex carbohydrates (polysaccharides) are the best choice for endurance athletes, as they allow your digestive system to rapidly and efficiently process a greater volume of calories, providing steady energy. Unlike simple sugars, which match body fluid osmolality at 6-8% solutions, complex carbohydrates match body fluid osmolality at substantially more concentrated 15-18% solutions. Even at this seemingly high concentration, complex carbohydrates (maltodextrins/glucose polymers) will empty the stomach at the same efficient rate as normal body fluids, providing up to three times more calories for energy production than simple sugar mixtures. This means that you can fulfill your caloric requirements without running the risk of overhydration or other stomach-related maladies.
To get the proper amount of easily digested calories, rely on fuels that use complex carbohydrates (maltodextrins or glucose polymers) only, with no added simple sugar as their carbohydrate source.
Hammer Gel and HEED are ideal for workouts and races of up to two hours, sometimes longer in certain circumstances. For longer workouts and races, select Perpetuem or Sustained Energy as your primary fuel choice.
Too many endurance athletes fuel their bodies under the premise, If I burn 500- 800 calories an hour, I must consume that much or I’ll bonk. However, repeating what Dr. Bill Misner stated earlier in The GUIDE, To suggest that fluids, sodium, and fuels-induced glycogen replenishment can happen at the same rate as it is spent during exercise is simply not true. Endurance exercise beyond 1-2 hours is a deficit spending entity, with proportionate return or replenishment always in arrears. The endurance exercise outcome is to postpone fatigue, not to replace all the fuel, fluids, and electrolytes lost during the event. It can’t be done, though many of us have tried. Simply put, your body can’t replenish calories as fast as it expends them (ditto for fluids and electrolytes). Athletes who try to replace calories out with an equal or near equal amount of calories in usually suffer digestive maladies, with the inevitable poorer-than-expected outcome, and possibly the dreaded DNF (Did Not Finish). Body fat and glycogen stores easily fill the gap between energy output and fuel intake, so it’s detrimental overkill to attempt calorie-for-calorie replacement.
Keep this in mind if you’re doing ultraendurance events, especially if you’ve had to alter the game plan and are unable to stick to your planned hourly caloric intake. For example, let’s say you’ve been consuming an average of 250 calories an hour, but the heat or other circumstances (such as climbing a very long hill) prevent you from maintaining that desired hourly average. DO NOT try to make up lost ground by consuming additional calories; it’s not only unnecessary, it may very well cause a lot of stomach distress, which will hurt your performance. Remember, during periods where fuel consumption may be less than your original hourly plan, body fat stores will effectively fill in the gap, thus eliminating the need to overcompensate with calories.
In general, an intake of 240-280 calories per hour is absolutely sufficient for the average size endurance athlete (approximately 160- 165 lbs/approx 72.5-75 kg). Lighter weight athletes (<120-125 lbs/ approx 54.5-57 kg) will most certainly need less, while heavier athletes (>190 lbs/approx 86 kg) may need slightly more on occasion, the key word being may.
When it comes to calorie intake, your focus should NOT be How much can I consume before I get sick? but rather, What is the least amount of calories I need to keep my body doing what I want it to do hour after hour? Start with our dosage recommendations as outlined in the article The Hammer Nutrition Fuels – What they are and how to use them (found in our supplementary booklet) and fine tune your intake as needed. As is the case in all aspects of fueling, when it comes to caloric intake you need to determine, via thorough testing under a variety of conditions, what amounts work best for you.
Consuming sufficient amounts of calories and fluids during workouts and races is an obvious necessity. Consistent electrolyte supplementation is equally important. Just as your car’s engine requires sufficient oil to keep its many parts running smoothly, your body requires electrolytic minerals to maintain smooth performance of vital functions such as muscle contraction. Athletes who neglect this important component of fueling will impair their performance, and may incur painful and debilitating cramping and spasms, a sure way to ruin a workout or race.
However, this doesn’t mean that athletes should indiscriminately ingest copious amounts of one or more electrolytes; sodium (salt) is usually the most misused. Supplementing with only one electrolyte or consuming too much of one or more electrolytic minerals overrides the complex and precise mechanisms that regulate proper electrolyte balance. The solution is to provide the body with a balanced blend of these important minerals in a dose that cooperates with and enhances body mechanisms. Salt tablets alone cannot sufficiently satisfy electrolyte requirements, and excess salt consumption will cause more problems than it resolves.
Additionally, remember that electrolyte replenishment is important even when it’s, not hot outside. Sure, you may not need as much as you would in hotter weather, but your body still requires consistent replenishment of these minerals to maintain the optimal performance of many important bodily functions. You don’t wait until you dehydrate before you drink fluids, or until you bonk before you put some calories back in your body, do you? Of course not. You fulfill your fueling requirements before the consequences of inadequate replenishment strike. The same principle applies to electrolyte replenishment. Going back to the engine/oil analogy, you don’t wait until the engine seizes before refilling the oil reservoir. The same is true for electrolytes, the body’s motor oil, in that you don’t want to wait until you start cramping before you replenish these important minerals.
Endurolytes, in capsule or powder form, is an inexpensive, easy-to-dose, and easy-to-consume way to get your necessary electrolytes. Use Endurolytes consistently during workouts and races to fulfill this crucial fueling need.
When exercise extends beyond about two hours, your body begins to utilize some protein to fulfill its energy requirements, as you begin to derive glucose from amino acids. This metabolic process helps to satisfy anywhere from 5-15% of your energy needs. If you fail to include protein in your fuel, your body has only one other choice: your own muscle! Called lean muscle tissue catabolism or muscle cannibalization, this process devastates performance through muscle deterioration and increased fatigue-causing ammonia accumulation, and also negatively affects the immune system and recovery. The longer your workout or race, the greater these problems are compounded. While carbohydrates are still the primary component of your fuel, it should include a small amount of protein when training sessions or races last longer than two to three hours. We believe that soy protein’s amino acid profile is ideal for use during exercise, which is why Hammer Nutrition’s Perpetuem and Sustained Energy contain soy as the protein source. For instance, compared to whey protein (which is ideal for recovery), soy protein has higher levels of phenylalanine and tyrosine, which may aid in maintaining alertness during ultra-distance races. Soy protein has higher amounts of histidine, which is part of the beta-alanyl l-histidine dipeptide known as carnosine, which has antioxidant/acid buffering benefits. Finally, soy protein has higher levels of aspartic acid, which plays an important role in energy production via the Krebs cycle.

“Soy’s remarkable donation to endurance performance is deserving of our review. Soy has been observed to produce a higher degree of uric acid content than whey proteins. Uric acid is reduced by excessive free radicals produced during exercise. When uric acid levels are higher, that is an indication of less free radical release due to antioxidant influence of the isoflavones found exclusively in soy. This is one reason why soy may be the preferred dietary protein application during endurance exercise.”

Using Perpetuem or Sustained Energy as your primary fuel during workouts and races longer than two to three hours will satisfy energy requirements from a precise ratio of complex carbohydrates and Soy Protein, the latter of which helps protect against excess muscle breakdown. You stay healthier, reduce soreness, and decrease recovery time.
In the 1985 Race Across America (RAAM), Jonathan Boyer rode to victory using a liquid diet as his primary fuel source. Since then, it has become the norm for endurance and ultra-endurance athletes. Liquid nutrition is the easiest, most convenient, and most easily digested way to get a calorie and nutrient-dense fuel. Solid food, for the most part, cannot match the precision or nutrient density of the best liquid fuels. In addition, too much solid food consumption will divert blood from working muscles for the digestive process. This, along with the amount of digestive enzymes, fluids, and time required in breaking down the constituents of solid food, can cause bloating, nausea, and/or lethargy. Lastly, some of the calories ingested from solid foods are used up simply to break down and digest them; in essence, these calories are wasted.
Occasional solid food intake provides a welcome diversion during ultra-endurance efforts, but we don’t recommend it as your primary fuel source. In fact, our position is that NO solid food is necessary (even food as healthy as the Hammer Bar) during workouts or races in the 12-hour-or-under range. If, however, you choose to consume solid food during your workouts or races, even during ultra distance events, we suggest you take heed to these two recommendations:
Use Hammer Gel, HEED, Sustained Energy, and/or Perpetuem as your primary fuel source during exercise. These provide precise amounts of specific nutrients and are designed for easy digestion, rapid nutrient utilization, and less chance of stomach distress. Also, the numerous flavors and mixing options give you plenty of variety. If you do decide to consume solid food, use it sparingly and select high-quality foods such as the Hammer Bar.
The title is pretty self-explanatory; it’s one of THE cardinal rules for all athletes, yet you’d be amazed at how many break it. Are you guilty as well? Unless you’re absolutely desperate and willing to accept the consequences, do not try anything new in competition, be it equipment, fuel, or tactics. These all must be tested and refined in training.
Because all of the Hammer Nutrition fuels are complementary (they all work well alone or in combination), you have all the flexibility you need to ensure that you can tailor a fueling program for any length of race, regardless of the conditions. You’ll never have to guess or grab something off the aid station table in the hopes of trying to keep going for another hour. Use Hammer Nutrition fuels, try a variety of combinations in training, and keep a log of what works best for you. If you expand your training log to include fuel intake also, you’ll have the data you need to prepare a smart fueling protocol for your next event.
Endurance athletes tend to be strong-willed and uncompromising. Most strive to have a game plan in place for their training program, which is, of course, an excellent idea. Smart athletes also have a strategy for their supplements and fueling. Having this nutritional game plan that you’ve honed during training is a big step toward success on race day, but don’t slavishly adhere to it during the race if it’s not working. What does fine in terms of fueling – your hourly intake of fluids, calories, and electrolytes, during training at a slower pace and lower overall energy output, might fail during competition. Athletes who stubbornly maintain the same fuel intake hour after hour, even when it’s clearly not working, end up with poorer results, if they finish at all.
Yes, it’s important to maintain consistent caloric intake during a workout or race, but if the weather gets hot, the body’s ability to process calories usually diminishes. It’s important to recognize this and to listen to your body. Continuing to force down X amount of calories an hour (the original game plan), especially under extreme conditions when your body cannot properly assimilate them, puts a burden on your stomach and can cause any number of stomach-related maladies, which will certainly hinder or ruin performance. In the heat, it becomes more important to stay hydrated and maintain adequate electrolyte levels, so be willing to cut back on calorie consumption. Body fat stores, which satisfy up to two-thirds of energy requirements during prolonged exercise, will accommodate energy needs during occasional breaks from regular intervals of fuel consumption. During the heat, fueling is still important, but the focus shifts towards maintaining hydration and proper electrolyte levels. Resume regular caloric intake when you start feeling more acclimated to the heat and your stomach has had some time to assimilate the fuel that it already has.
In a similar, but non-fueling vein, another time when it’s not a wise idea to stick to your training plan is after you’ve had a poorer-thanexpected race. Many athletes think that the cure for a poor race is to train harder and longer. Instead of recuperating, many athletes will train themselves into the ground, usually ending up not fitter, but overtrained, with a poorly functioning immune system. A better tactic is to recuperate completely after your race, evaluating what went right and what went wrong during the race, then adapting your training accordingly; training harder and longer isn’t necessarily your best option. Remember that recovery is as important a part of your training and the achievement of your athletic goals as the actual training session. Make sure that you take your recovery as seriously as your training.
It’s a good practice to have a game plan that includes a fueling protocol that you have refined during training, but you need to be flexible. Evaluate and adjust accordingly as race pace and weather dictate. Have a game plan, but write it in pencil, not in ink.
Performance improvement depends on a program of exercise that stimulates muscular and cardiovascular adaptation followed by a recovery period in which the body rebuilds itself slightly more fit than before. Thus, the real gain of exercise occurs during recovery, but only in the presence of adequate rest and nutritional support. Athletes who fail to replenish carbohydrates and protein shortly after workouts will never obtain full value from their efforts. So even though all you may want to do after a hard workout is get horizontal and not move for several hours, you must first take care of what might be the most important part of your workout: the replenishment of carbohydrates and protein.
Carbohydrate replenishment as soon as possible upon completion of a workout (ideally within the first 30-60 minutes) takes advantage of high glycogen synthase activity, imperative to maximizing muscle glycogen, the first fuel the body uses when exercise commences. Protein supplies the amino acids necessary to (a) maximize glycogen storage potential, (b) rebuild and repair muscle tissue, and (c) support optimal immune system function.
This is also an ideal time to provide the body with cellular protection support in the form of antioxidants. Because athletes use several times more oxygen than sedentary people, they are more prone to oxidative damage, which not only impairs recovery but is also considered a main cause of degenerative diseases. Consistent supplementation with a full spectrum vitamin/mineral supplement, along with any additional antioxidants, boosts and maintains the immune system and reduces recovery time.
The bottom line is that post-workout nutrition is an important component of your training, and properly done, allows you to obtain maximum benefit from your training.
Depending on a number of factors (such as body size and length/intensity of the workout), consume 30-90 grams of complex carbohydrates and 10-30 grams of protein (a 3:1 ratio of carbohydrates to protein) immediately after workouts. This is easily accomplished with Recoverite, the all-in-one, complex carbohydrate/ glutamine-fortified whey protein isolate recovery drink. Supplements to consider for providing antioxidants and supporting enhanced recovery are the Hammer Nutrition products Premium Insurance Caps, Race Caps Supreme, Mito Caps, Super Antioxidant, AO Booster, and Xobaline.
Far too often, athletes put themselves at a metabolic disadvantage during a workout or race by fueling improperly prior to it. The article PROPER FUELING – Pre-workout & race suggestions* discusses this in greater detail, but we mention it here as well because it’s definitely one of the biggest fueling errors that athletes make. It’s also one that is easy to remedy. Let’s look at the three primary factors:
Don’t go overboard with your food consumption the night before a workout or race. Especially important for races is the adherence of these two rules:
If you’re going to have a pre-race meal the morning of your race, you need to eat an appropriate amount of calories (don’t overdo it), and finish your meal at least three hours prior to the start of the race. If that’s not logistically feasible, have a small amount (100-200 calories) of easily digested complex carbohydrates 5-10 minutes prior to the start. Either of these strategies will help top off liver glycogen stores (which again, is the goal of the pre-race meal) without negatively affecting how your body burns its muscle glycogen.
If you’re going to have a meal the morning of your workout or race, you need to eat an appropriate amount of calories (don’t overdo it), and finish all calorie consumption at least three hours prior to the start of the workout or race. If that’s not logistically feasible, have a small amount (100-200 calories) of easily digested complex carbohydrates 5-10 minutes prior to the start. Either of these strategies will help top off liver glycogen stores (which again, is the goal of pre-exercise calorie consumption) without negatively affecting how your body burns its muscle glycogen.
Far too many athletes overdo it in terms of calorie, fluid, and salt consumption in the days leading up to a race, thinking they’re getting a head start on their fueling needs come race day. Big mistake! Here are the fueling/diet-specific areas to focus on and our recommendations on how to avoid these commonly-made mistakes:
On a non-diet/fueling note, avoid the temptation to train too much and/or too close to race day. You will not be able to positively influence your fitness level in the days leading up to the race; however, you can negatively impact your race by training during that time (training meaning anything of significant duration or intensity). As well-known coach Jeff Cuddeback states, ” If you think you’re going to further your fitness through training the week of your key race, you’re sadly mistaken. If you are the type to train right up to the event, you will almost certainly underperform.”
The best performances in long-duration events are achieved by getting to the starting line well rested rather than razor sharp. In doing so, you may find yourself not hitting on all cylinders during those first few minutes. In fact, you might even struggle a bit. However, your body will not forget all the training you’ve done and it will absolutely reward you for giving it the time it needed to “soak up” all of that training.
