What keeps a triathlon athlete going in spite of the heat and long hours of vigorous physical activity is a properly hydrated and fueled body. In endurance sports, nutrition is equivalent to keeping oneself hydrated at all times, especially during the game. If you don’t give yourself the proper nutrition it needs, your game performance will suffer.

Sports that require special attention to endurance nutrition (and thus help you level up your performance) are: running, swimming, triathlon, cycling, rowing, mountain biking, adventure racing, cross-country skiing, mountaineering and trekking.
