Abstract

Purpose: The objective of this study was to investigate whether ultramarathon runners were able to meet nutrition recommendations during a training period and on a competition day. Methods: In preparation for a 60 or 120 km ultramarathon covering a varied terrain, male and female ultramarathon runners (n=68, age 46.5±7.1 y) reported habitual dietary intake during three independent days using a web-based 24-hour recall and questionnaires. The diet was assessed using probability of inadequacy or by qualitative evaluation using reference dietary intakes or sports nutrition recommendations. A small group of 120 km runners (n=4) was observed continuously during the race. After the race, 60 km runners (n=41) received a questionnaire to assess dietary intake and gastrointestinal (GI) distress on the race day. Spearman rank correlation coefficients (r) were applied to investigate the association between intake and general GI distress symptoms. Results: In men and women, habitual mean carbohydrate (CHO) intake was lower than recommended, as was mean protein intake by women. CHO intake during the race was
