There is little information about the actual nutrition and fluid intake habits, and gastrointestinal (GI) symptoms of athletes during endurance events. PURPOSE:: To quantify and characterize energy, nutrient and fluid intakes during endurance competitions and investigate associations with GI symptoms. METHOD:: 221 endurance athletes (male and female) were recruited from two Ironman triathlons (IM Hawaii and IM GER), a half-Ironman (IM70.3), a MARATHON, a 100/150 km CYCLE race. Professional cyclists (PRO) were investigated during stage-racing. A standardized post-race questionnaire quantified nutrient intake and assessed 12 GI symptoms on a scale from 0 (no problem) to 9 (worst it has ever been) in each competition. RESULTS:: Mean CHO intake rates were not significantly different between IM Hawaii, IM GER and IM70.3 (62±26, 71±25 g/h and 65±25 g/h, respectively), but lower mean CHO intake rates were reported during CYCLE (53±22 g/h, p=0.044) and MARATHON (35±26 g/h; p
