The food and fluid intake of a male ultraendurance runner was recorded throughout a 1,005-km race completed over 9 days. The nutrient analysis showed an average daily energy intake of 25,000 kJ with 62% from carbohydrate, 27% from fat, and 11% from protein. Carbohydrate intake was estimated to be 16.8 g · · . The protein intake was estimated to be 2.9 g · · and water intake to be 11 L per day. These figures are within the recommended levels for ultraendurance athletes (2, 10). Food and fluid were consumed in small amounts every 15 to 20 min to ensure maintenance of blood glucose levels and adequate hydration. This case study suggests that if the guidelines for prolonged exercise are followed, then athletes can successfully complete ultraendurance events.
