Some research has found that inclusion of small amounts of protein during prolonged activity can help enhance performance by sparing muscle glycogen as well as aiding fluid uptake. Protein also can help mute hunger that arises during longer efforts.

Athletes on restrictive energy intakes should aim for the high end of this recommendation. Race Morning: Include grams of protein in the hour leading up to race start to help stabilize blood sugars.

Common pre-race protein sources include peanut butter, non-fat milk or yogurt, eggs, and energy bars. During Race: If out on a training or race course longer than 4 hours, aim for up to 5 grams of protein hourly.

Common sources include sports drinks, energy bars, as well as whole food alternatives like turkey jerky and peanut butter sandwiches. Post-Race: A range of grams of protein taken immediately post-race is sufficient to support muscle repair and immune function post-event. Common sources include milk, meal replacement shakes, and specialized recovery sports drinks.

Replacement of electrolytes becomes instrumental in endurance bouts lasting longer than 1 hour, especially when training and racing in hot and humid conditions.

The principle electrolytes include sodium generally bound to chloridepotassium, magnesium, and calcium. These electrolytes are involved in metabolic activities and are essential to the normal function of all cells, including muscle function.

Pre-Race: Athletes vulnerable to muscle cramping and fatigue as well as those competing in heat may benefit from increasing salt intake in the few days leading up to race day. Many of the carbo-loading options, such as pretzels, sports drinks, breads, and cereals, accommodate this.

Similarly, on race morning, choosing saltier carbohydrate sources, such as a salt bagel, and sipping on a sports drink rather than plain water may help. Salt loading is not recommended for athletes on blood pressure medications.

During Race: Aim for mg of sodium per standard bike bottle of water consumed ounces as well as smaller amounts of potassium, magnesium, and calcium. Note that too much sodium can lead to bloating and GI discomfort so be sure to account for all your sources, including sports drinks mg per 8 ozenergy gels mg per packet and chews mg per 3 piecessalt packets ~ mg per packetand electrolyte capsules ~ mg per capsule.

Post-Race: Sipping on a sports drink, rather than plain water, post-race will facilitate optimal rehydration of muscles, including replacement of lost electrolytes. Because water serves as the medium for all metabolic activity, helps to lubricate our muscles and joints, and also keeps our core body temperature in check, failure to take in enough fluids during a long run can have a dramatic negative impact on both health and performance.

Therefore, determination of sweat rate and consequent fluid demands is extremely important for athletes. Daily: Drink half your body weight in pounds in fluid ounces or so urine runs pale yellow during the day. For example, a lb man requires approximately 75 ounces of fluid daily. Unfortunately, this level of dehydration can have significant negative consequences on performance so be sure to sip on ounces of fluid in the hours leading up to race start or so that urine runs pale yellow.

During-Race: Aim for ½-1 liter or approximately 1 standard bike bottle ~ ounces per hour or so that urine runs pale yellow. It is important to note that over-hydration, also known as hyponatremia, can be just as dangerous as dehydration and is generally caused by consuming fluids, especially water, beyond that of what the body can absorb.

Cardinal symptoms of over- hydration include clear urine, pressure headaches, nausea, vomiting, and confusion. To monitor hydration status, weigh in pre- and post-workout. It is estimated that one needs approximately 20 ounces of fluid to replenish 1-lb of body weight.

A central nervous system stimulant, caffeine may help maintain blood glucose concentration and reduce power loss through its effects on the active musculature and nervous system that reduce fatigue and perceptions of effort, discomfort, and pain.

Specific flavors of energy gels and chews are caffeinated at a dose of mg pack. It is important to experiment with personal tolerance to caffeine as some athletes do not respond favorably to caffeine with symptoms such as a racing heart beat, muscle twitching, stomach distress, and anxiety serving as reason for avoidance.

Aim for mg of caffeine e. Avoid consuming more than mg of caffeine on race day. For best results, consider eliminating caffeine from the diet for 10 days prior to racing.

Put simply, carbohydrates are sugars and starches that fuel our bodies much like gasoline fuels a race car. Each gram of carbohydrate contains ~4 calories worth of fuel. Just like a race car stores its fuel in a tank, the human body stores carbohydrates as glycogen in both our muscles and liver. These glycogen reserves are relied upon to stabilize blood sugars and allow for optimal muscle function.

Nutritional considerations for multi-stage endurance events -

There is considerable debate about whether an ultramarathon runner might have a performance benefit from dietary carbohydrate or fat manipulations, ketogenic adaptation, or simply training in a glycogen depleted state to enhance fat oxidation Burke, ; Impey et al.

However, high fat oxidation rates also appear to be inherent in ultramarathon runners regardless of background macronutrient dietary modifications. Determining whole-body fuel utilization during ultramarathon events presents challenges and complexities, which will impact on the magnitude of exercise stress, and subsequently dictate fuel kinetics Howe et al.

Although a comprehensive evaluation of dietary manipulation in ultramarathon runners has not yet been completed, positive correlations of preexercise dietary carbohydrate manipulations and during running and carbohydrate intake with performance outcomes are consistently observed in endurance models, which may be applicable to ultramarathon runners Smith et al.

Further research is needed, however, to investigate the potential role of dietary carbohydrate and fat manipulations specific to ultramarathon running performance. Due to the wide variation in ultramarathon events, the logistics of race nutrition management vary dramatically.

However, some general factors appropriate for all events can be considered. With this in mind, ultramarathon runners are unlikely to fully replace energy expenditure acutely and need not plan on carrying full energy requirements.

Alternatively, they should strive to logistically organize and consume what is feasibly tolerable Table 1. Does not include water i. c Approximately 0. Avoiding an excessive energy deficit is best accomplished with nutrient dense foods and fluids, which have been consumed in training that mimics race conditions, and is adequately tolerated.

To avoid carrying excessive amounts of nutritional items during the event and therefore unnecessary pack weight, ultramarathon runners should determine in advance which nutritional items will be available during the event and assess such items in training.

Furthermore, it is important to determine whether certain foods are available in the race country, since local choices can vary widely. Regardless of this, appetite dysfunction, taste fatigue, and gastrointestinal symptoms are common during ultramarathon events Costa et al.

Finally, if nutrients are being largely or exclusively consumed in liquid form, caution should be taken to avoid hyperhydration and associated health complications e. It is well established that carbohydrate consumption during exercise enhances endurance performance Smith et al.

Research that has formed the basis for feeding during endurance exercise consensus guidelines and recommendations Thomas et al. It appears that such high levels of carbohydrate intake during running are not achievable by the majority of both elite and amateur ultramarathon runners Costa et al.

Given that general aerobic fuel oxidation rates for ultramarathon running have not yet been fully explored, applying the guidelines and recommendations for shorter endurance exercise could be erroneous.

Therefore, individual specific assessment for carbohydrate gastric emptying and intestinal transit, digestibility and absorbability, and oxidation rates during exercise stress is recommended.

For example, assessment might include: 13 C labeled food or fluid ingestion or lactulose challenge followed by breath sampling and analysis with or without electrogastrography to assess gastrointestinal transit functional responses; specific i.

Practical Nutrition Recommendations to Support Individualized Strategies During Participation in Ultramarathon Running Events.

Gastrointestinal symptoms have been reported as a major factor limiting nutritional intake during and after ultramarathon events, withdrawal from competition, and are linked to severe clinical episodes of acute colitis with accompanying fecal blood loss Costa et al.

The causes of adverse gastrointestinal symptoms during and after ultramarathon running appear to be multifactorial in nature but are likely related to splanchnic hypoperfusion and increased sympathetic drive, which results in clinically significant secondary outcomes, such as epithelial injury and permeability; impaired gastrointestinal function; and systemic responses i.

The management of extrinsic e. Adapted from Costa et al. inconclusive, unknown, and or conflicting efficacy. a Splanchnic hypoperfusion, and subsequent intestinal ischemia and injury including mucosal erosion results in direct e. b Amino acids glutamine, l -arginine, and l -citrulline.

Proper management of hydration is critical for both performance and overall health in ultramarathon running. Similar hydration mismanagement has been observed during multistage and hr ultramarathon events Costa et al.

The present review will focus on aspects of hydration unique to ultramarathon participation Table 3 , which may vary in comparison with hydration needs of shorter endurance running events see Casa et al.

Practical Hydration Recommendations to Support Individualized Strategies During Participation in Ultramarathon Running Events. During the hours or days of running while participating in ultramarathon events, proper hydration involves maintaining adequate fluid intake to avoid performance limiting hypohydration, while also avoiding excessive fluid intake with potential for developing exercise-associated hyponatremia EAH; Hew-Butler et al.

However, it has been suggested that such conditions do not necessarily translate into field-based scenarios Wall et al. On the other hand, hyperhydration is the primary risk for the development of EAH, from which a number of fatalities have been reported during various activities Hew-Butler et al.

Fortunately, to date, we are unaware of any EAH-related deaths in ultramarathon events. Hyperhydration can also decrease performance indirectly by increasing body mass and unnecessary fluid carrying, time delays for drinking and filling fluid containers, and pauses required for urination. In addition, excess fluid intake may result in an overwhelming gastric load i.

Thus, avoiding hyperhydration or hypohydration is recommended for both health and performance in ultramarathon running.

Proper hydration during ultramarathon running requires the understanding that all fluid losses need not be replaced, as body mass loss from endogenous substrate oxidation is expected Hoffman et al.

It is also recognized that water is produced during fuel oxidation and that some water linked with glycogen may be released in response to oxidation of endogenous glycogen stores.

However, the extent of availability of these water sources to support the intravascular water pool remains controversial, and the proper proportion of body mass loss during endurance running is not completely clear.

On the contrary, others consider thirst to be an inadequate stimulus to maintain proper hydration Armstrong et al.

However, past recommendations emphasizing this were largely intended for situations in which dehydration might develop rapidly from high sweat rates associated with high exercise intensities Hew-Butler et al.

Indeed, considerable evidence has demonstrated that drinking to thirst during ultramarathons, even under hot ambient conditions e.

Thus, adequate fluid intake during ultramarathon running can generally be achieved by simply drinking fluids ad libitum, as long as there is adequate access to fluids when desired. When fluid access is limited, it is essential for runners to estimate the fluid volume required to carry between sources to support thirst i.

This is best done through experience, while recognizing variability in the appropriate fluid intake with exercise intensity and ambient conditions. It has, however, been demonstrated that supplemental sodium is not necessary to maintain euhydration during ultramarathon competition, even under hot ambient conditions Hoffman et al.

Moreover, sodium intake during exercise will also not prevent EAH in the presence of hyperhydration Hew-Butler et al. Thus, best practice suggests avoiding attempts to replace all sodium lost in sweat through the intake of sodium supplementation during ultramarathon running, recognizing that considerable sodium is present in the typical race diet e.

While considering nutrition and hydration guidelines and recommendations for general endurance exercise may provide some guidance and support for shorter running events and ultramarathon training, caution is warranted in using these guidelines for ultramarathon competition due to the large diversity of participant demographics and event characteristics.

It is unlikely that full energy and nutritional provisions can be met during single-stage and multistage ultramarathons; however, developing training and race nutritional strategies to ameliorate the potentially extreme deficit will support training and event performance, and also contribute to the prevention or attenuation of any associated health complications of subclinical or clinical significance.

Submit Comment. Over the last few weeks we have been writing about hydration and nutrition strategies for a multi-stage race. In this article, we look at how to tailor your nutrition to encourage recovery.

Multi-stage racing requires you to push hard for a day and then do it again and again. The focus needs to be providing your muscles with the right things to repair and re-synthesise glycogen stores.

In short: recovery is as important as running! There are two important timing windows which competitors need to be aware of, a short and a longer one:. The short phase occurs within the first 30 minutes post-exercise and is the most important period for recovery and feeling good the next day.

Carbohydrates should make up the bulk of your immediate recovery nutrition and also a good hit of protein a ration is recommended. Carbohydrates, not protein, are responsible for replenishing glycogen stores.

However, you will need the protein to repair any muscle damage. This crucial phase comes just after the finish line and so you might not feel like doing anything other than lying down, yet it is vital that you use this window to take on board some calories.

As you might not have the appetite nor the stomach for a full meal, it is best to have a snack or recovery shake ready to mix when you finish. Some example products which competitors have used in our events are: SIS Rego, TRIBE Recovery Shake, or For Goodness Shakes. The second window to be aware of lasts longer.

This subsequent recovery phase of fuelling lasts until you creep into your sleeping bag. Whilst the focus of the first window should be kicking off the recovery process, this second window is a time to top up the tank.

Similar to the initial post-race phase, consuming some protein with carbohydrate can lead to higher muscle glycogen synthesis, and it is recommended to aim for
