In contrast to shorter endurance events, food and fluids were equally important for providing CHO in this ultraendurance race. Athletes participating in ultraendurance events should familiarize themselves with available food and fluid choices on race day and develop a compatible nutritional strategy to integrate into their daily training. Planning of race-day provisions is also important, but flexibility is necessary to allow for changes according to the athlete’s tolerance, environmental conditions, and opportunities for food and fluid intake on race day.
