But what, when, and how much to eat and drink can Ednurance confusing for even the most experienced endurance athlete. The following Weight management nutrition provide some general guidelines to nutritioh simplify your Blood pressure diet and refueling plan.
These foods fall race three general categories: carbohydrates, Endurajce, and protein. Carbohydrates are the main nutrients racs fuel moderate to high-intensity exercise.
These foods supply the body racfs glucose it needs for continued and sustained energy. Eating them enables endurance athletes nurition keep going without " bonking ," in which your blood sugar drops too encurance and you can't continue. Yet, research indicates that most non-elite endurance athletes don't consume Enduarnce necessary amount of carbohydrates to support their hefty training schedule.

This foor be broken Endurance nutrition for endurance races by pre- and post-training recommendations, as well as suggestions for refueling during an endurance training or event.
Eating three to four hours before engaging in endurance training or events helps the body start off with a full fuel Racew. Often referred to as endurwnce the best food Encurance for this pre-training meal enddurance complex carbohydratesor carbs that take the Energy conservation tips longer to digest.
Glycogen stores have a limited supply and get used up rather quickly—within about 90 racez to two hours—during high-intensity enduarnce. Endurance nutrition for endurance races not adequately replenished, fatigue sets in and the athlete needs to slow down or risk "hitting the wall.
That's why it is important to consume carbohydrates throughout long training sessions or endurance events. The best carbs for this purpose are simple carbsor carbs that the body can digest rather quickly. After the endurance training session or event, the body needs to refill its energy tank.
More carbs can assist with this, but protein is important at this point too, providing your muscles the nutrients needed to adequately recover.
Many of the best post-workout snacks provide the carbohydrates needed to rebuild your energy stores. Each category of macronutrients carbs, protein, and fat includes certain foods that offer higher nutritional value, making them better choices for fueling and refueling the body.
Here are a few to consider. Offering a mix of carbohydrate sources, for example, these dietician-recommended energy chews, gels, and bars help provide sustained energy. Since pre-training eating involves consuming complex carbs, healthier foods that fall into this category include:.
To continue high-level exercise for extended periods of time, athletes benefit from fueling their body during the training session with easily digestible or "fast" carbohydrates.
Some good mid-exercise refueling options that won't weigh you down include:. Protein helps the body heal, making it a great after-training food source.
Healthier protein food options include:. However, the body does need some fat to function effectively. Fats that are healthier include:.
Just as it is important to know what to eat and when, endurance athletes also benefit from understanding how much to eat. This ensures that you obtain the needed nutrients in the right amount without consuming too many calories and potentially gaining weight. Intake recommendations for endurance athletes are: .
When calculating your body weight, one kilogram is equal to 2. So, a pound person weighs roughly 68 kilograms divided by 2. If you exercise intensely for more than three or four hours at a time, you need to be mindful of your hydration needs and drink water before, during, and after you exercise.
Don't rely on thirst to tell you when to drink during exercise. By the time you feel thirsty, you're already dehydrated. It's best to drink small amounts often, rather than gulping a lot at once. Get into the habit of weighing yourself before and after long training sessions to determine your individual hydration needs and to learn how different weather and training conditions may affect you.
Another simple way to determine your post-workout hydration status is to monitor your urine output and color.
A large amount of light-colored, diluted urine most likely means you are well-hydrated. A small amount of dark-colored, highly concentrated urine may mean you are dehydrated and need to drink more water. The following tips can help you stay on top of your fluid needs while exercising:.
Rehydrate by drinking about 24 ounces of water for every kilogram 2. This helps support optimal performance, both physically and mentally. A quick and easy option is to consume an electrolyte-containing sports drink during the training or event.
This can help reduce the risk of developing hyponatremiawhich is water intoxication caused by below-normal sodium levels.
Some types of protein bars also contain electrolytes. Every athlete will have their own unique fueling and refueling needs and preferences. By experimenting with different approaches, you will find the approach that works best for you.
Try various foods and food combinations before, during, and after your workouts. Vary the timing of your food intake and the amount you eat as well and, over time, you will be able to determine your optimal refueling style. Burke L, Hawley J, Jeukendrup A, Morton J, Stellingwerff T, Maughan R.

Consider them ballpark figures, which you can adjust based on your own experience. If possible, top off your glycogen tanks with a carb-rich meal 3 to 4 hours before your event. One thing truly magical about being an endurance athlete is that you're part of a tiny demographic that actually benefits from tall-stack pancake breakfasts. Juice and gels are great options. If you want to keep it natural, low-fiber fruit such as bananas and dates are also good choices. Avoid fiber, protein, and fat in the hours before your race. Digestion requires blood flow around your gut. Exercise requires blood flow around your extremities. When the two compete, no one wins. So just keep them steady until actively avoiding them a couple hours before the start. Favor foods that do double duty, providing both carbs and complete proteins. Since many athletes, especially cyclists, try to keep weight down, this can be scary. Current research shows that, for endurance athletes, as little as a 2 percent dip in body weight due to dehydration can have a huge impact on performance. One study showed that once that number slipped below 3 percent, time trialing cyclists experienced a 2. Another study from showed that cyclists who hyperhydrated hydrated their bodies above their normal states prior to a 2-hour event experienced a decrease in heart rate and perceived thirst, but an increase in time to exhaustion and peak power output. You should be drinking plenty of water leading up to your event, but things become critical 2 to 3 hours before starting. Second, you should feel the need to pee frequently, and that urine should have a pale, yellow color. Many people feel they get adequate hydration through the water in foods and coffee or tea. There may be some validity to these beliefs for the masses, but not for athletes. At least one study showed that runners who drank a high sodium drink before exercise experienced less perceived strain during exercise, as well as increased exercise capacity in warmer weather. The obvious reason for this is that when you sweat, you lose sodium along with other electrolytes, which can have a huge impact on many systems in your body, including those governing muscle function. Formulas like LADDER Hydration can be a great option in this scenario, which contains mg of sodium per serving. Endurance training can be grueling. And the events themselves tend to be even bigger beat-downs. So relax and enjoy it — while you can. The Importance of Carbs First, some nutritional Carbs The primary job of carbohydrates is to provide energy. Fat As I said, your body also likes to use fat both adipose tissue and dietary fat as fuel, but it needs a little more processing than carbs. |

| Endurance race nutrition plan | Again, make sure to read the ingredients to verify the sugar sources. So make a point of being fully fed and hydrated before you start your race and focus on fueling the moment you hit terra firma. Have a full bottle either by your bike or in your transition bag to sip as best you can as you change. If you can chomp a chew or two during transition without slowing down, great. Otherwise, make a point of feeding during the first few miles on your bike. Treat this transitional fueling like any other part of your training. While protein is instrumental post-event, it should play very little part in during-event feeding. Your goal is to restore glycogen as fast as humanly possible, and protein slows absorption. The exception is a multi-stage race. In this case, you want to maintain the balance of protein turnover the synthesis and degradation of muscle as much as possible, so some protein during such an event is a good idea. Just keep carbs at the forefront of your feeding, and experiment with protein during training to figure out how much you can tolerate. While all of this advice gives you an excellent starting point for event nutrition — or hopefully a way to troubleshoot your current method — keep in mind that personal taste and biology go a long way towards determining the right foods for you. Never, ever experiment during a race. Find the intersection of what works scientifically and what works personally. By Denis Faye, M. To avoid running on an empty tank, here's how to fuel your body during a race. Fight fatigue and replenish electrolytes during races with LADDER Hydration! Shop all premium supplements. How Your Body Burns Fuel When You Exercise When you exercise, your body can pull fuel from a few places: Adipose tissue through lipolysis — the breakdown of fat Muscle mass through proteolysis — the breakdown of protein Carbs through glycolysis — the breakdown of glucose, AKA blood sugar, which is also stored in muscle and liver cells as glycogen. Glycogen and Energy Levels Glycogen is basically a back-up blood sugar supply. Drinking Your Carbs The science behind event feeding is surprisingly vague, but the science behind event hydration is relatively solid, so by pinning that down, you can simplify the feeding part. What Should You Eat? A Word About Protein While protein is instrumental post-event, it should play very little part in during-event feeding. The Final Word: Do Whatcha Like While all of this advice gives you an excellent starting point for event nutrition — or hopefully a way to troubleshoot your current method — keep in mind that personal taste and biology go a long way towards determining the right foods for you. How to Eat Leading Up to Your Big Endurance Event. Food such as peanut butter sandwiches do not travel very well. The second issue is the ease of which the food item can be consumed. Again, a peanut butter sandwich is pretty messy and tricky to eat while doing an event. This is where gel packets come in real handy. Just tear them open and enjoy. You can stash a couple either in pockets or even carry in your hands. Just please remember to discard the container and not just throw to the side of the road. Following an event , you should eat carbohydrates to replace depleted glycogen stores and lean protein to enhance the speed of recovery and reduce soreness. Some options can include fruit juice, yogurt, and chocolate milk. For your next meal following an endurance event you should emphasize foods like potatoes, pasta, breads, and vegetables.

| Endurance race nutrition strategies | This includes:. In addition to the three macros, endurance athletes also benefit from some specific micronutrients. Two to consider are vitamins C and D. Vitamin C is perhaps best known for boosting immunity. But it also serves other important purposes. One is that it is an antioxidant, protecting the cells against free radical damage. Another is that it supports wound healing. According to a study , vitamin C also helps athletes recover during the competitive season 2. Citrus fruits and potatoes are high in vitamin C. So are peppers, broccoli, strawberries, and kiwi. Vitamin D is important for bone health. Weak bones mean more fractures and breaks. A study also ties adequate vitamin D levels with improved athletic performance 3. Taking a cod liver oil supplement is one way to get more of this nutrient. Orange juice and dairy are also high in vitamin D. We lose water throughout the day. It escapes our body through normal respiration, sweating, and urinary output. When we exercise, we lose more. Staying hydrated is more than about satisfying thirst. The top reasons for proper hydration, which are especially important for clients taking on endurance events, include:. Endurance athletes need to watch their hydration throughout the day, especially during workouts. Water intake guidelines are provided by the National Academies of Sciences, Engineering, and Medicine 4. Current guidelines are 2. This includes water consumed both from beverages and food. When your client is taking part in endurance activity, they need to up their intake. Here are some recommendations to follow:. After endurance exercise: 24 ounces for every pound of body weight lost. In addition to water loss through sweating, we also lose electrolytes. When we sweat, we lose sodium, chloride potassium, magnesium, and calcium. These electrolytes serve important roles in supporting bodily systems. There are many electrolyte drinks on the market. These can help replace lost nutrients. Many exist in the form of a sports drink. The problem is that these drinks can also be high in sugar and calories. One of the best ways to replenish electrolytes after a long endurance training session is by eating whole foods. Here are a few options to consider:. Potassium - banana, sweet potato, dried fruits, avocado, kale, peas, beans. Magnesium - whole grains, leafy vegetables, nuts, lentils, peanut butter. Achieving peak performance requires having nutrients available when you need them. This can be accomplished by developing a nutrient intake plan. And this plan should provide nutrient timing guidelines. Timing the intake of carbohydrate, protein, fat, and water is essential to endurance success. It involves laying out what to consume before, during, and after endurance training and endurance events. Consume 20 ounces of water 2 hours before the start of endurance training. Carbohydrate loading should only occur leading up to an endurance event. Consume 1. Consume 15 to 25 grams of protein within the first 30 minutes post-exercise. Nutrition for endurance involves a lot. But when endurance athletes pay attention to the recommendations and figure out what methods work best for them, the outcome is improved athletic performance. This can translate to higher awards come race day. Whether you are an elite athlete, a weekend warrior, or a personal trainer designing programs for athletes, it is important to fuel the body properly. Proper nutrients at the right time allow the body to perform at its highest level. Want to learn more about nutrition and its impact on sports performance?

This includes: Fatty fish - salmon, mackerel, or tuna Avocado Seeds - sunflower, sesame, and pumpkin seeds all have healthy fats Nuts - peanuts, walnuts, almonds, or cashews Olive oil Eggs Ground flaxseed Beans - kidney, navy, or soybeans. Featured Course. First Name. Last Name. One of the big trends in sports nutrition over the past decade has been the idea that, instead of just eating the same things every day, you should adjust your intake to match your expenditures. Olympic Committee that offers visual guidance for how you might eat during periods of light, moderate, and heavy training. You can see the three plates here. On the easy training plate, vegetables and fruits take up half the plate. Grains and fats are good options, along with subtler tweaks. For example, the easy training plate includes only fresh fruit; the moderate and hard plates add stewed and dried fruits. In practice, that means cutting way back on fiber for a few days. Researchers at Liverpool John Moores University in Britain tested this approach in a study published earlier this year. They had 19 volunteers cut back from their typical 30 grams of daily fiber to less than 10 for four straight days, while maintaining the same overall calorie content and macronutrient distribution in each meal. The result: average weight loss of 1. There are other reasons you might be interested in a pre-race low-residue diet. She noted four relevant and evidence-backed ergogenic aids for track athletes: beta-alanine, sodium bicarbonate, creatine, and caffeine. Only the last one has been shown to reliably work for long-distance events. She also noted some key parameters to monitor on an ongoing basis: vitamin D, vitamin B12—and iron. The risk of low iron is a familiar topic for endurance athletes. One of the particular challenges for athletes is that heavy exercise produces elevated levels of a hormone called hepcidin, which interferes with iron absorption for up to six hours after training. As a result, Sygo suggests taking supplements away from training time, ideally on an empty stomach, with vitamin C to aid absorption. She also noted a further twist: U. |
Endurance nutrition for endurance races -
Because glycogen stores are limited, and because they provide a critical contribution to both anaerobic and aerobic energy production, one important objective of sports nutrition is to protect glycogen and enhance access to fat for long duration, moderate intensity activity. In contrast to dietary fat, body fat stores are of tremendous importance during physical activity, as long as the intensity is not too high and there is adequate O2 delivery to use fat as a fuel source.
Compared to the finite capacity of glycogen, fat stores can usually supply more than 70, kcal for activity 3. Fat is stored mainly in the adipose tissues and some is stored in muscle cells.
Endurance training increases the capacity for fat metabolism in the muscles, so that fat metabolism will cover a greater proportion of the energy production of athletes during exercise than for untrained people.
Additionally, if the intensity of activity is low enough to allow aerobic energy pathways to predominate, the athlete will have optimal access to fat as an energy source. This will preserve glycogen and minimize the utilization of protein for fuel. While fat and carbohydrate represent the largest contribution of energy expenditure during exercise, the utilization of protein can also be significant.
It is preferable to reserve protein as a building material, for the synthesis of lean skeletal tissues and contribution to other body systems for which protein is essential i. Therefore, one objective of sports nutrition is to minimize protein utilization during activity through consuming enough carbohydrate.
This will spare proteins from being broken down to create glucose, a process called gluconeogenisis. While there is little debate that protein needs are greater for highly active individuals than those less active, this is often explained as a function of total energy intake 4.
However, the specific percent contribution of protein to total daily intake for endurance athletes has been in question for some time. The scientific literature to date provides some sound evidence to support an increase in protein requirements for highly-trained and elite endurance athletes 5.
Tarnopolsky found that acute endurance exercise results in the oxidation of several amino acids. Based on the available literature, sports nutritionists estimate protein requirements for an endurance athlete to be 1. An examination of each nutrient in isolation, while interesting, has limitations.
For example, an adequate protein intake with inadequate carbohydrate or calories will still result in suboptimal nutrition and performance. Regardless of how athletes divide up their macronutrients, if total energy intake is not adequate, performance will suffer 7.
A review study of the nutritional needs of endurance athletes concluded that endurance athletes often have negative energy balance, meaning that expenditure is higher than intake 8. This negative balance can compromise performance and will definitely influence the percent contribution of each macronutrient.
Perhaps of even greater consequence than macronutrient distribution is the total energy intake in relation to expenditure. If organized in priority order, fluid would sit at the top of the list. While not energy-yielding, fluid plays a critical role in optimal performance and safe athletics.
The combination of heat stress, dehydration, and exercise imposes perhaps the most-severe physiological challenge for the human body short of disease or serious bleeding Exercise requires the body to attempt to cope simultaneously with competing demands for cardiovascular homeostasis, thermoregulatory control, and maintenance of muscle energetics.
When dehydration is superimposed upon this scenario, the results can be catastrophic for both health and performance. Sweat evaporation provides the primary cooling mechanism for the body, and for this reason athletes are encouraged to drink fluids to ensure continued fluid availability for evaporation and circulatory flow to the tissues.
A water loss of even one to two percent of body weight can reduce an individual's capacity to do muscular work The major electrolyte in sweat is sodium with smaller amounts of potassium and magnesium. Loss of substantial amounts of sweat will inevitably reduce the body's reserve of these electrolytes, which can also impair performance.
Conversely, excessive drinking can lead to hyponatremia severe enough to cause fatalities. In addition to securing the right macronutrient distribution, athletes should be encouraged to make the most nutrient dense choices possible.
While a discussion of micronutrients is outside the scope of this article, if athletes are taking in adequate calories and making healthful food choices, they will be better protected against vitamin and mineral deficiencies as well.
Timing also is critical and must be individualized to the sport and to each athlete. Nutrients taken during endurance competition should be primarily carbohydrate sports rehydration beverages, carbohydrate gels and goos and other carbohydrates to deliver this valuable fuel when glycogen may be running low.
Likewise, eating carbohydrates after a training session will enhance glycogen storage and some research indicates that a combination of carbohydrate and protein will further promote glycogen replenishment There are numerous considerations in designing nutrition protocols for individual athletes.
As with other any sport, maximizing the nutritional needs during endurance competition begins in training. The competitive advantage will definitely shift in favor of those athletes whose coaches and trainers recognize the fundamental value of fitness, acclimation, hydration, and nutrition for keeping athletes cooled and fueled.
Training can use up as much as 40 percent of an athlete's total daily energy expenditure and energy demands in competition can also be very high. Successful implementation of sport nutrition guidance requires that coaches, athletes, and support personnel are made aware of the practical benefits of adequate fluid replacement and nutrient needs.

Fitness Sports Performance Nutrition Nutrition and the Endurance Athlete - Eating for Peak Performance. By Dominique Adair, MS, RD Nutritional needs of the endurance athlete are aggressively studied and the days of the pre-marathon pasta dinner have been enhanced by a sophisticated understanding of how nutrients can improve long-duration performance.
The following all influence which fuel is predominant during activity: intensity anaerobic or aerobic of activity duration of activity conditioning of the athlete recovery time diet composition Muscles always use a mixture of fuels, never just one. Carbohydrates For Endurance Athletes Glucose, stored in the liver and muscles as glycogen, is vital to physical activity.
FatS for Endurance In contrast to dietary fat, body fat stores are of tremendous importance during physical activity, as long as the intensity is not too high and there is adequate O2 delivery to use fat as a fuel source. Protein And Endurance Training While fat and carbohydrate represent the largest contribution of energy expenditure during exercise, the utilization of protein can also be significant.

Such solutions tend to absorb more efficiently and effectively. A good sports drink will offer carbs as a combination of fructose and glucose. Second, consuming only one item for hours on end while suffering mentally and physically is a recipe for flavor fatigue — where you achieve such a distaste for nourishment that your exhausted, exercise-addled brain actively prevents you from eating or drinking.
By mixing liquids and solids, you stand a better chance of avoiding flavor fatigue and maintaining your appetite. Anything that tastes good and consists primarily of carbs will probably work.
You want to absorb those sugars fast, so high-glycemic foods i. Some of my go-tos include bananas, melon, other low-fiber fruit, and mini-pretzels. Three to four hours into an especially hard event, I also take great pleasure in an eight-ounce can of Coke.
Hooray for carbs and caffeine! But if your event is going to be consistently grueling or jarring on your system — triathlons and marathons come to mind — gels and chews are both easy-digesting feeding options.
Again, make sure to read the ingredients to verify the sugar sources. So make a point of being fully fed and hydrated before you start your race and focus on fueling the moment you hit terra firma. Have a full bottle either by your bike or in your transition bag to sip as best you can as you change.
