“…For athletes participating in events lasting several hours, glycogen supercompensation along with carbohydrate replacement during exercise is necessary for sustained performance. To avoid potential injury and decrements in performance that may result from classical carbohydrate loading (3,17), athletes are advised to employ for several days a modified regimen of tapered training and increased carbohydrate intake to 80% of total energy intake for glycogen supercompensation (38). In light of an ultraendurance athlete's training frequency and prolonged training hours (31), he or she may not sufficiently taper prior to competition to allow for maximal glycogen supercompensation.…”

The nutritional considerations of the ultraendurance athlete center around proper caloric and nutrient intake during training as well as adequate energy and fluid replacement during competition to maintain optimal performance. Energy needs of ultraendurance athletes during training vary widely, depending upon duration, intensity, and type of exercise training. These athletes may train several hours daily, thus risking inadequate caloric intake that can lead to chronic fatigue, weight loss, and impaired physical performance. It is not known whether protein needs are increased in ultraendurance athletes as a result of extended exercise training. Additionally, micronutient needs may be altered for these athletes while dietary intake is generally over the RDA because of high caloric intake. Prior to competition, ultraendurance athletes should consider glycogen supercompensation and a prerace meal eaten 4 hrs before as a means of improving performance. Carbohydrate feedings during prolonged exercise can significantly affect performance. During events lasting over several hours, sodium sweat losses andlor the consumption of sodium-free fluids may precipitate hyponatremia.With the recent popularity of endurance sports such as distance running and cycling, a new group of athletes have emerged who participate in endurance events of ultra distance. These athletes engage in prolonged exercise sessions lasting several hours-even days-in events such as ultradistance marathons 90-200 km, Ironman distance triathlons (3.9-km swim, 180.2-km bike, 42.2-km run), open-water swims of 10 km or more, and bicycling races of 200 to 4,000 km or more. Participation in ultradistance sporting events requires extended training sessions which often represent multiple daily training sessions. To meet rigorous training demands, ultraendurance athletes must consider ways to exercise performance through dietary manipulation and energy replacement strategies during exercise that will optimize work performance.Ultraendurance athletes, as well as other athletic groups, are gaining an appreciation and understanding of the role of nutrition in athletic performance. carbohydrate intake prior to and during athletic competition, for instance, is
