These snacks will help to mjlti-day your energy levels up and sustain your enery. If levvels are doing a longer endurance training day, it's a good idea to have a meal higher multii-day carbohydrates and lower in durint, such as pasta or a sandwich.

The next step is to Maintaining energy levels during multi-day endurance events your meals and Maintaaining ahead of time. You will need a mix event carbohydrates, Maintaining energy levels during multi-day endurance events and healthy mulit-day to help fuel your body and keep your energy levels up.

Aim to eat a meal or snack every hours to keep your energy levels steady. Choose easily digestible foods,such as oatmeal, fruit, nut butter and toast, or a protein bar. It is most important to ensure that you are drinking regularly throughout the event.

This will help to keep your energy levels up and prevent dehydration and fatigue. Some of my favorite snacks and drinks are bananas, peanut butter, DripDrop oral rehydration in a bottle of water, watermelon and various nuts. Sometimes, you just need some sugar. Honey or Gatorade is effective in adding quick fuel to your body in these situations when you are starting to feel light-headed, dizzy or nauseated from low blood sugar.

This should keep you fueled to keep going and salted to help prevent muscle cramps and debilitating heat exhaustion -- or worse. When it comes to hydration, make sure you have a water bottle that is easy to carry and refill throughout the day. Remember, you have minutes to go without water and only a few hours to go without food or fuel sources when staying fit to complete these types of long endurance events.

If you run out of water, you are done shortly thereafter. Make sure that your last meal before the event is a good mix of carbohydrates, proteins and fats. This will provide your body with the fuel it needs to endure the long event.

If you are taking part in a tactical training day, consider having an energy bar or a sandwich before you start to ensure your body has a steady source of energy. Finally, you should also be aware of your body's temperature and environment. In hot or humid environments, you will need to drink more water to stay hydrated.

If you're in cold temperatures, you will need to make sure you have enough calories to keep your body warm. If you're feeling cold, eat some high-calorie snacks such as peanut butter, nuts, trail mix or protein bars.

By following these tips, you will stay energized and hydrated during long endurance and tactical training events. Plan ahead, bring the right food and drinks with you and don't forget to listen to your body and its needs.

Eating a calorie surplus, staying hydrated and having snacks on hand can help you make it through your event. Just find the ones that agree with you and your energy demands and tastes.

Maintaining energy levels during multi-day endurance events -

The team must stay together at all times. Extreme environmental conditions and challenging topography can both be features of adventure races. Nutrition plays a crucial role in the successful completion of adventure races, to ensure adequate energy intake and prevent dehydration, particularly in extreme temperatures.

Typically, competitors must carry their own race nutrition and be self-sufficient throughout the race. Adequate fuelling will not only sustain physical performance, but optimise concentration and mental stamina required for effective course navigation.

The specific energy demands and optimal physiological requirements will vary for the different components of an adventure race. Limited data exists on adventure racers, although typically a relatively low body mass and low body fat are considered optimal to be competitive.

A high energy diet is often required to support the training and competition demands of adventure racers, though individual needs can be highly variable.

Training load and body composition goals are two factors that may impact individual energy targets. A heavy training block for an ultra-endurance adventure racer results in very high daily energy expenditures.

Adequate energy intake will support optimal performance and completion of demanding training volumes. High energy requirements can be achieved with frequent meals, nutrient dense foods, adequate portion sizes and appropriate intake before, during and after training sessions.

Protein requirements are increased due to the higher protein needs for endurance exercise, with protein intake ideally being spread over the day.

Including a variety of healthy fats in the diet e. avocado, oily fish, olive oil , nuts, seeds is important for health and immune function and overly fat-restrictive diets should be avoided. A variety of colourful vegetables and fruit daily will provide essential nutrients such as fibre, antioxidants, vitamins and minerals.

Although a low carbohydrate high fat diet can influence fuel utilisation and increase fat oxidation during sub maximal sustained exercise, currently there is insufficient research to indicate a performance benefit from a high fat diet for endurance athletes.

Fluid requirements vary between individuals largely depending on sweat rate, which can be influenced by intensity, fitness level, and weather conditions. Athletes should aim to start training and races well hydrated and continue to optimise hydration throughout.

For shorter training and event duration water is the best rehydration fluid. Longer races at lower intensity however can favour adequate fluid consumption. Dehydration can lead to fatigue, loss of concentration and impaired performance due to loss of power and intensity.

For longer duration adventure races, i. duration of 4 hours or more, carbohydrate loading for days prior to race day can allow muscle glycogen stores to be maximised. An Accredited Sports Dietitian can provide a race nutrition plan that includes a tailored carb loading plan to reduce gastrointestinal upset while optimising fuel stores pre-event.

The ideal pre-event meal will provide sufficient fuel and hydrate you without leaving you feeling uncomfortable. Timing is important to consider to allow for food to be digested and move out of the stomach prior to the race commencing. Consumption of carbohydrates during performance has also been shown to be beneficial to best conserve muscle and hepatic glycogen storage and to maintain blood glucose concentration.

Again, however, this appears to have practical difficulties. Mahon et al. These carbohydrates can also be provided in gel or bar form as it was recently demonstrated that carbohydrates in a beverage are oxidized at similar rates to carbohydrates from a gel [ 53 ] and from a bar [ 54 ].

Further ways to increase intake during events through management of gastrointestinal symptoms GIS will be discussed in the section on gastrointestinal intolerances. Dietary fat is essential for optimal health and should not be overlooked by those engaging in ultra-endurance events.

After 2—3 weeks on this diet, the body is able to adapt to using fat at greater contributions, sparing more carbohydrate [ 57 ]. With a reduced reliance on carbohydrates as a fuel source as well as the elimination of the need to consume carbohydrates during activity, many potential advantages are presented.

The athlete would no longer be required to carry sources of CHO with him or her, worry about attaining enough CHO or risk GIS from eating during activity.

However, this strategy also comes at a cost. This reliance on fat limits the intensity of exercise that can be performed and severely restricts the capacity to do anaerobic work [ 57 , 58 ]. In a study on mountain ultramarathon runners, Mahon et al.

This further supports the need for CHO intake during prolonged events, given that ketones are an indicator of fat metabolism, particularly if an objective is to complete the event in minimal time.

It is also important to note that in non-fat adapted athletes low CHO availability increases muscle protein breakdown [ 59 ] and if performed chronically can lead to a loss of skeletal muscle mass. However, naturally during multi-day events, exercise pacing tends to conform to submaximal levels of intensity, often below lactate threshold to preserve limited glycogen stores and optimize fat utilization and the Krebs cycle pathway for ATP resynthesis [ 60 ].

This being said, fat adaptation is worth experimenting with for those who consume far below the recommended intakes of energy and carbohydrates for their events, particularly for those who are prone to GIS.

Bringing calorie intake closer to energy expenditure using fat also improves performance when compared to a larger caloric deficit without extra fat [ 61 , 62 ]. Since fat is more calorically dense than protein and carbohydrate, athletes who must carry their own food should choose high fat food options if it allows them to reach closer to their caloric needs over carbohydrate.

Therefore, this strategy may be most appropriate for those competing in ultra-events which have breaks and which athletes must carry their own food. Although preloading with dietary fat, specifically medium chain triglycerides MCT , has strong literature support to potentially improve performance based on its capacity to serve as a fuel source and spare muscle glycogen [ 63 , 64 ], the majority of studies have found no glycogen preserving effect or improvement in shorter distance endurance performance [ 65 — 70 ].

In longer duration activities, the research is conflicting. A study by Van Zyl et al. Contrary to this, Jeukendrup et al. The difference in the results of these two studies is likely due to the quantity of MCT ingested by the participants. Van Zyl et al. provided 86 g in total whereas Jeukendrup et al.

provided 29 g in total. However, an intake of 86 g far exceeds the recommended maximum by many authors 30 g who suggest intakes higher than this lead to gastrointestinal discomfort and diarrhea [ 71 — 73 ].

A later study by Jeukendrup et al. At this time, the literature does not support the use of MCT supplementation in ultra-endurance activity. Protein is a critical nutrient requiring considerable attention by the athlete to ensure proper recovery from exercise and to promote optimal adaptation between training sessions.

The protein needs of athletes engaging in prolonged activity are greater than those required for the general population because of the need to repair damaged muscles and synthesize new muscle proteins.

It further serves as an energy substrate during activity [ 75 ]. When it comes to increased metabolic efficiency with training, a certain degree of metabolic efficiency does occur to mitigate amino acid oxidation with training [ 95 ], however, the rate of oxidation still increases over 2 h of endurance activity resulting in a several fold increase compared to resting conditions regardless of training level [ 96 , 97 ].

Due to both the use of amino acids as a fuel source as well as muscle damage associated with exercise, skeletal muscle mass seems to decrease in ultra-endurance running events without breaks, as has been shown in a few case reports of ultra-endurance athletes [ 3 , 78 ].

In contrast, in ultra-endurance events where there are breaks, skeletal muscle mass tends to remain stable [ 79 — 81 ]. When muscle loss occurs from walking or running, with the exception of the thigh, it has been shown to occur in all muscle groups with the greatest losses occurring in the lower leg or calf region [ 3 , 82 , 83 ].

The eccentric contractions involved in running cause the greater portion of body mass lost as muscle mass comparatively [ 82 ] to more concentric-based ultra-endurance activities such as cycling [ 84 ]. One way in which athletes may reduce the amount of endogenous protein lost, and by extension, promote recovery, is by ensuring adequate glycogen stores going into exercise and by consuming adequate energy during prolonged activity [ 35 ].

The following recommendations can also help ensure athletes are recovering lost muscle and preventing loss of skeletal muscle mass during training and events. Although the pre-eminent adaptations in resistance exercise compared to endurance exercise may be different, the requirements for amount, type, and timing are similar [ 75 ].

Protein remodeling, which is primarily determined by changes in muscle protein synthesis, is an important aspect of the acute recovery process after exercise that ultimately underpins the adaptations e.

Numerous studies have reported increases in mixed muscle protein synthesis following a single bout [ 85 , 86 ] of exercise, and both short-term i. The current recommended intake of protein is 1.

Given the extraordinary caloric needs to fuel these unique tasks, it is likely that these athletes are meeting and possibly exceeding this recommendation if they are meeting their energy requirements [ 76 ].

In addition to daily protein needs, other factors are also important for optimizing performance adaptations, including timing and partitioning of intake. To maximize protein synthesis, and thus muscle remodeling and recovery [ 89 ], it is suggested that endurance athletes consume a minimum of 20 g of protein at 3—4 h intervals to maximize muscle protein synthesis [ 75 , 90 ].

The amount required for ultra-endurance athletes and those who exercise longer than 2 h is presently unclear. However, it is likely that their needs would be even higher given the increase in total oxidation of amino acids during exercise as well as the possibility of splanchnic organ tissue damage due to the shunting of blood away from the digestive system during activity [ 91 ].

The rate of muscle breakdown is accelerated when muscle protein oxidation exceeds synthesis, which usually occurs in proportion to intensity and duration of the sporting activity [ 92 — 94 ]. It has been posited that supplemental protein or amino acids on top of this intake during an ultra-run may improve performance through provision of amino acids for use as a fuel source and to attenuate muscle damage [ 99 ].

Despite the use of supplementary amino acids having been shown to improve performance and decrease muscle soreness in cyclists, a study on ultramarathon runners showed no benefits.

Knechtle et al. Contrary to their hypothesis, there were no improvements in performance or effects on parameters related to skeletal muscle damage in the supplemented group. Unfortunately, measures of skeletal muscle damage were only taken immediately after the race.

More research is needed to determine if the intake of amino acids during the race would lead to lower values of these markers in the following hours and days of recovery. Therefore, at the present time, evidence would suggest no additional benefit from consuming supplementary amino acids or protein during ultra-endurance running events.

In comparison to resistance exercisers, the immediacy of dietary protein intake after exercise is critical for optimal recovery [ , ]. The consumption of a snack or meal with a minimum of 20 g of protein within 30—60 min post exercise is suggested to optimally stimulate muscle protein synthesis and attenuate any existing breakdown that is ongoing from the bout of prolonged exercise [ 75 ].

Hoffman et al. In other activities such as shorter duration endurance events, hydration needs for an event can be approximated during training through methods such as taking body weight before and after training at a duration, intensity, and environment that mimics that of a competition [ ].

However, because reductions in body mass can be attributed to substantial breakdown of body tissues such as adipose and muscle [ 11 ] and increases in weight can result from reduced diuresis as well as decreases in intracellular osmolytes including glycogen, proteins, and triglycerides, this would be an ineffective strategy for ultra-endurance athletes.

The reduced diuresis is induced by activation of vasopressin secretion and the angiotensin—renin—aldosterone mechanism during exercise and the decreases in intracellular osmolytes causes a shift of water to the extracellular compartment during very prolonged exercise [ ].

With the complexity of hydration during these events, hyper-hydration has become increasingly common and is the most reported medical complication to occur during ultra-distance triathlons [ ].

This is crucial as this can lead to the life-threatening case of hyponatremia by altering the blood serum to sodium ratio [ ].

In fact, this shift appears to be a primary result of fluid overload and is unrelated to sodium losses [ ]. Urine color see Fig. However, it should be noted that urine concentration i. Costa et al. found that it is in fact less reliable than relying on thirst as an indicator of hydration status [ 15 ].

It is important to note here that substrate metabolism is also altered as a result of dehydration during exercise resulting in greater reliance on carbohydrate as a fuel source [ ].

Although the fatigue associated with dehydration is mainly a result of hyperthermia it also results in lower FFA uptake and higher muscle glycogen utilization [ ]. Therefore, not only is maintaining hydration important for sustaining an optimal body temperature, preventing immediate fatigue, but it is also important to spare glycogen, potentially preventing or delaying later onset of fatigue.

Urine color as an indication of hydration status reproduced with permission from [ ]. Because sweat also contains sodium one might argue that sodium supplementation may be of importance during ultra-endurance walking and running events.

Although past recommendations suggest a sodium intake of 1. This is likely due to the adaptations that increase sodium bioavailability and prevent losses e. sweat, urine, and feces which take place in response to periods of sodium deprivation or restriction [ — ]. In fact, sodium supplements taken in excess can result in inadequate weight loss and even unnecessary weight gain [ ].

This ultimately results in fluid overload and decrements to performance as discussed above. It is therefore recommended that to best maintain hydration, athletes drink to thirst without using sodium supplementation beyond that taken in food and fluids, even when exercising in high ambient temperatures [ ].

Other recommendations for maintaining euhydration during the event pertain to both the use of carbohydrate supplemented beverages and fluid intake before the event.

This will allow enough time for excretion of any excess as urine before the event allowing for a balanced bodily fluid level going into the activity [ 45 ].

Vitamin and mineral considerations are crucial when participating in and training for ultra-endurance activities. When it comes to athletic performance, these micronutrients are particularly important for energy production, hemoglobin synthesis, maintenance of bone health, adequate immune function, and protection of the body against oxidative damage.

They also assist in important physiological processes related to synthesis, recovery, and adaptation to exercise. Because of this, exercise may increase the turnover and loss of these nutrients resulting in greater dietary intakes being required. Some vitamins and minerals that athletes need to pay particular attention to are calcium, vitamins D, C, E, and the B vitamins, iron, zinc, magnesium, as well as, beta carotene and selenium for their antioxidant properties.

Calcium and vitamin D play important roles in growth, maintenance, and repair of bone tissue as well as regulation of nerve conduction, and development and homeostasis in skeletal muscle. A deficiency in both or either calcium and vitamin D increases the risk of low bone-mineral density and stress fractures [ ].

Calcium can be obtained from food; however, vitamin D is mainly synthesized through sunlight. In those with suboptimal levels stated in Table 2 , supplementation may be necessary. Current vitamin D supplement recommendations suggest — IU per day for athletes [ ].

B vitamins play a role in energy production and the building and repair of muscle tissue. There is some data suggesting that to obtain optimal health and performance, highly active athletes may need to double the current recommended amounts of these B vitamins though it is likely that these needs are being met with increased energy intakes [ ].

Of particular consideration, however, are vitamin B12 and folate. A deficiency in either of these nutrients results in anemia which can greatly reduce time to fatigue and therefore endurance performance [ ].

Because vitamin B12 is obtained through animal products, such as meat and dairy, athletes such as vegetarians or vegans may need to consume supplements with this vitamin.

Iron deficiency will also result in anemia, reducing the ability of red blood cells to transport oxygen. A deficiency in iron is common among those engaged in prolonged activity due to up-regulation of the hormone hepcidin.

Because of this, ultra-endurance athletes should pay particular attention to their iron consumption and obtain regular blood tests to check their ferritin status.

Iron absorption can be improved by consuming heme iron found in meat products with non-heme iron found in plant products and vitamin C with sources of iron [ , ]. Zinc plays a role in muscle repair, energy metabolism, and immune status. A deficiency in zinc can result in disrupted thyroid hormone levels, affecting metabolic rate and performance [ ].

It can also reduce cardiorespiratory function, muscle strength, and endurance [ ]. Athletes are at high risk of inadequate zinc levels [ ] and should therefore strive to achieve adequate zinc intake through zinc-rich foods.

Zinc-rich foods include shellfish, green leafy vegetables, and seeds. If supplementation is required, athletes should receive guidance from their health care provider.

Magnesium supports the proper functioning of the nervous and musculoskeletal systems [ ]. Deficiency can cause multiple symptoms resulting in decreased performance as it is linked to many pathological conditions of the cardiovascular, skeletal, and nervous systems [ ].

Ultra-endurance athletes are at increased risk of this deficiency due to increased urinary and sweat losses induced by magnesium redistribution within the body during prolonged intense activity [ ].

Ultra-endurance athletes should have their blood levels of magnesium tested regularly and self-monitor for common symptoms of hypomagnesaemia such as muscle cramps.

Supplementation with magnesium is recommended if necessary and dosage should be determined under the discretion of their healthcare provider to avoid toxicity.

Exercise can induce a release of free radicals or reactive oxygen species which have the ability to modify lipids, proteins, carbohydrates, and nucleic acids in the body [ ]. These modifications are collectively known as oxidative damage or oxidative stress and have been linked to negative health outcomes such as insulin resistance, atherosclerosis, cardiac dysfunction, and injury [ ].

Antioxidant vitamins and minerals, such as vitamins C and E, beta carotene, and selenium can be used to mitigate these effects. These nutrients act in different ways to either remove oxidative species or prevent their reactions from happening [ ].

However, because oxidative species also have some beneficial effects on the body, their function is not to completely eliminate these processes, but to keep them at homeostatic, and thus optimal, levels. Therefore, there is a threshold to which antioxidants can provide benefits for performance, health, and recovery.

Research on ultra-endurance athletes has demonstrated that their need to prevent oxidative damage is higher given their extraordinary exercise volume [ ]. Although more research is needed to examine the effects of these antioxidant supplements during and immediately prior to an event, current evidence suggests little to no benefit [ , ].

It is important to note that although ultra-endurance athletes may benefit from ample intakes of antioxidant vitamins and minerals that exceed the current recommendations for the general population, they should be cautioned not to consume these nutrients at levels above the ULs.

High doses above the UL can also result in pro-oxidative effects, causing risks of decreased performance, recovery and health [ ]. Other antioxidants which have recently been investigated for their effects on endurance performance include polyphenols with the most popularly researched being quercetin, catechins, and resveratrol.

These polyphenols are organic chemical compounds mainly found in plants that have strong antioxidant properties [ ]. They have also been shown to have anti-inflammatory, cardioprotection, and anti-carcinogenic properties in clinical populations [ ].

However, few studies have investigated the effects of these polyphenols on performance, particularly in an ultra-endurance population. Catechins are commonly found in plants such as green tea and cacao. Some human studies have shown positive effects for endurance including V02 max [ ], fat oxidation, and insulin sensitivity [ ] in an untrained population; however, studies on trained subjects are yet to show benefits [ — ].

It is unlikely that supplemental catechins would be beneficial to ultra-endurance performance. Resveratrol is present in concentrated quantities in grapes.

With one exception, studies to date have only been performed on rodents, and the effects on performance range from extremely beneficial to extremely detrimental [ — ]. Taken together, these studies would suggest that resveratrol benefits trained rodents and is potentially harmful in untrained rodents.

The only human study was performed in untrained elderly participants and the effect demonstrated that supplementation was also potentially harmful through blunting of cardiovascular training adaptations to endurance exercise [ ]. Further research is needed before supplemental resveratrol should be taken by ultra-endurance athletes.

Quercetin is found in foods such as red onion, dill, apples and capers and has been studied more extensively than other polyphenols. It provides many health benefits in humans [ ] and has shown to encourage mitochondrial growth in rodents [ ].

Although quercetin supplementation shows potential endurance performance benefits in cell culture and in vivo animal studies [ , ], research on its use as a supplement in humans are less clear.

Some studies have reported increased endurance exercise capacity and performance in humans following supplementation with quercetin [ — ]; however, many have failed to find benefits [ — ].

Of the 2 studies [ , ] on ultra-endurance trained subjects, both have shown no significant benefit. Nieman et al. No improvements in performance or attenuation of markers of muscle damage, inflammation, increases in plasma cytokines, and alterations in muscle cytokine mRNA expression were found [ ].

Quindry et al. The supplement did not fortify plasma antioxidant levels against ultramarathon-induced oxidative stress in blood plasma or improve performance.

This being said, a meta analysis by Kressler et al. Based on data showing favorable outcomes for supplemental quercetin [ — ], a daily dosage of mg could have small potential benefits and is unlikely to be detrimental for ultra-endurance trained populations.

However, the amounts needed in excess of those recommended for the general population are likely dependent on multiple factors including individual variability, training intensity, and training duration.

To determine if ultra-endurance athletes are consuming adequate amounts of vitamins and minerals, they should obtain regular blood tests to ensure blood levels are being maintained at levels that are not only acceptable for general health but are optimal for performance see Table 2.

This may be particularly important during times when their training or nutrition changes. It is important to emphasize that regular adequate intake of vitamins and minerals is required for optimal performance and that consuming extra vitamins and minerals through supplementation immediately before or during an ultra-endurance event has not shown to provide any performance, health or recovery benefits [ , ].

During ultra-endurance activities and corresponding training exercises, food and fluid must be consumed while being active to minimize the energy deficit. Because of this, it is no surprise that GIS are a common issue for these athletes [ ].

Endeavoring to prevent GIS is important as it is one of the most common cited reasons for inadequate intake during events [ , ] and is positively correlated with increasing duration [ ].

Running in particular appears to result in more pronounced GIS than other activities [ ] as well as a dehydrated state compared with a euhydrated state [ ]. There also seems to be an individual predisposition for GI distress during exercise as Pfieffer et al.

have determined a positive relationship between GIS during races and history of GI issues both associated with and away from exercise [ , ]. Another common issue in ultra-endurance athletes is reduced appetite, which is closely related to GIS as both are subsequent results of splanchnic ischemia.

If the event has no enforced breaks, whole foods may not be an option as they may be too difficult to chew and swallow and could result in GIS.

In this case, intake from fluids is a viable option as not only does it provide the energy but also hydration. With gels, it has been shown that high doses of CHO 1.

Against this background, it may be best to determine strategies, such as use of different types of nutritional sources and frequency of consumption to find which methods work best to maximize carbohydrate intake during an event without causing GI distress.

One of the possible ways that this could be done is through coingestion of glucose and fructose as a carbohydrate source rather than one or the other. Research suggests that this can increase carbohydrate oxidation from an average of 1—1. With the use of gels as a source of carbohydrates, Pfeiffer et al.

However, some individuals showed more symptoms with one or the other gel. It should, therefore, be advised that individual athletes, especially those who experience GI problems frequently, test their tolerance during intense training sessions, ideally under conditions similar to those of the races they aim to compete in.

The intake of the nutrients fat, fiber, and protein, have all been linked to GIS during exercise [ ]. However, as the duration of ultra-endurance races increases, these food and drink choices have become less tolerable and appealing [ , ]. Although the evidence of this is mainly anecdotal, intestinal carbohydrate transporters can indeed be up-regulated [ , ] and gastric emptying rates can be enhanced with training [ ].

GIS occur less frequently after adequate training or when relative exercise intensity is reduced [ , ]. Although more research in this area is needed, experimentation with this strategy during training is likely to present little risk and athletes should dedicate at least some time to gut training.

Endurance training itself appears to enhance gastric transit time [ ], and higher energy intakes during training further enhance this rate [ ]. Cox et al. The higher rates were attributed to improved absorption, which provides evidence that the gut is indeed adaptable and that this could be used as a practical method to increase exogenous carbohydrate oxidation.

This could lead to improvements in performance through greater fuel availability as discussed in preceding sections. There is a paucity of agreed-on and concrete nutrition best practices for ultraendurance runners and even less demarcating such by event type. From a macronutrients perspective, ultra-endurance athletes need to ensure adequate intake.

However, the practicality of such recommendations needs to be considered on an individual basis and the importance of rehearsal of an individualized nutrition strategy prior to competition cannot be overemphasized.

As far as is necessary, and in keeping with advice from healthcare providers, ultra-endurance athletes may use supplements to support training and events performance and aid in recovery.

While some recommendations presented are prescriptive in nature based on the findings of various studies, ultra-endurance athletes are encouraged to apply them within the context of their particular training regiment, body mass composition, and corresponding physiological needs.

All the literature reviewed indicate that ultra-endurance athletes must take great care in attending to their nutritional needs to maintain good health, promote optimal performance, and reduce the likelihood of injuries.

Proper nutrition will result in decreased energy depletion, better performance, and accelerated recovery. With the growing international appeal of ultra-endurance events, significant research is needed to promote the health and wellbeing of athletes.

More longitudinal studies are needed to ascertain the precise nutritional and environmental conditions under which athletes perform most optimally based on age, gender, type of event, body type, and other physiological factors.

4 Powerful Ways PRO Athletes Recover Faster (YOU CAN TOO) Maintaining energy levels during multi-day endurance events

Maintaining energy levels during multi-day endurance events -

Sometimes, you just need some sugar. Honey or Gatorade is effective in adding quick fuel to your body in these situations when you are starting to feel light-headed, dizzy or nauseated from low blood sugar. This should keep you fueled to keep going and salted to help prevent muscle cramps and debilitating heat exhaustion -- or worse.

When it comes to hydration, make sure you have a water bottle that is easy to carry and refill throughout the day. Remember, you have minutes to go without water and only a few hours to go without food or fuel sources when staying fit to complete these types of long endurance events.

If you run out of water, you are done shortly thereafter. Make sure that your last meal before the event is a good mix of carbohydrates, proteins and fats. This will provide your body with the fuel it needs to endure the long event. If you are taking part in a tactical training day, consider having an energy bar or a sandwich before you start to ensure your body has a steady source of energy.

Finally, you should also be aware of your body's temperature and environment. In hot or humid environments, you will need to drink more water to stay hydrated. If you're in cold temperatures, you will need to make sure you have enough calories to keep your body warm.

If you're feeling cold, eat some high-calorie snacks such as peanut butter, nuts, trail mix or protein bars. By following these tips, you will stay energized and hydrated during long endurance and tactical training events. Plan ahead, bring the right food and drinks with you and don't forget to listen to your body and its needs.

Eating a calorie surplus, staying hydrated and having snacks on hand can help you make it through your event. Just find the ones that agree with you and your energy demands and tastes.

To maximize carbohydrate uptake into the muscles and extend endurance, choose products whose ingredient lists include multiple types of carbohydrate. Common carbohydrate sources used in sports foods include maltodextrin, glucose or dextrose, sucrose, and fructose.

Common products used on race day include sports drinks, energy gels, energy bars, and energy chews. Post-Race: Aim for grams of carbohydrate, preferably in liquid form to promote rehydration as well as carbohydrate repletion, as soon as possible upon finishing a hard workout or race effort.

During digestion, protein is broken down into at least individual chemical building blocks known as amino acids that form a little pool within our liver and are used to build muscle, skin, hair, nails, eyes, hormones, enzymes, antibodies, and nerve chemicals.

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.

Triathletes should avoid eating only a starch by itself because it will raise blood glucose levels quickly and could lead to overeating during the taper. Stabilizing body weight is a primary goal of all triathletes leading up to a race, and as mentioned previously, this is typically difficult to control because of decreases in training volume.

Athletes should not overeat and try to overcompensate their caloric intake in an effort to load before competition.

Most athletes who follow a balanced eating program consisting of moderate carbohydrate, moderate protein, and low to moderate fat should continue this type of eating during their taper. Frequency of eating may be a variable that triathletes can consider changing, meaning they may not need to eat as many times throughout the day.

Eating to train during a taper becomes a good mantra to follow, and since training is reduced, so should food intake. Competition Day Race-day nutrition is highly individual for all triathletes, and the race distance and start time will dictate much of what a triathlete can consume the morning of a race.

The following general recommendations pertain to early-morning races: A smaller breakfast made up of moderate carbohydrate, moderate to low protein, and low fat is recommended. A liquid snack or meal such as a smoothie may be beneficial for those who have very sensitive stomachs.

Athletes should hydrate but should pay attention to not overhydrating with water alone as this can increase the risk of hyponatremia. Consuming water with salty foods or a sports drink with sodium is recommended.

For athletes competing later in the day, a normal breakfast that has worked for the athlete during higher-intensity training can be eaten followed by an easily digestible snack 1 to 2 hours before the race. Liquid sources are typically preferred.

After the race, it is common for athletes to forget about their nutrition. The postrace nutrition plan is crucial for allowing an athlete to replenish glycogen and fluid stores. The basic guidelines on what to eat in the first 15 to 60 minutes after a race include higher carbohydrate, moderate protein, and minimal fat and fiber.

Athletes should plan ahead of time to ensure that foods or beverages are available after their race. After the initial feeding, athletes should try to eat well-balanced meals consisting of carbohydrate, protein, and fat specifically omega-3 or monounsaturated 2 hours after the first postrace feeding.

If a fiber taper was implemented before a race, it is important to reintroduce fiber slowly into the normal daily nutrition plan by reversing the recommendations stated previously. That is, increase fiber gradually by 25 percent each day after the race to allow the body to get used to the normal amounts without causing GI distress.
