Introduction: there has been an increase in the number of endurance sports events during the last 20 years, as well as in the number of their participants. An adequate nutritional plan is essential for a satisfactory performance in this type of events, both in professional and amateur athletes. Objectives: the objective was to determine, evaluate, and compare with the current scientific recommendations the consumption of carbohydrates, water, and sodium by participants in a trail-running event. Methods: the competition completed by the athletes was the "Medio Trail de Alcoy 2019" (Alcoy, Spain), with a distance of 30 km. After completing the race, participants filled out a questionnaire about their food and drink consumption during the event, in addition to other questions about their nutritional habits in general. Eleven participants who met the inclusion criteria were included in the study. Results: the result obtained for average carbohydrate intake was 14.93 g/h, for sodium intake was 146.42 mg/h, and for water intake was 399.73 mL/h. In all, 27 % of participants visited a dietitian-nutritionist on a regular basis, and none reported gastrointestinal tract issues during the race. Conclusions: the carbohydrate and sodium consumption of participants was low as compared to current scientific recommendations; however, water consumption was adequate according to them. Our advice for endurance athletes is visit a specialized dietitian-nutritionist to achieve optimal performance in competitions.
在过去20年中，耐力运动赛事的数量及其参与者的数量都有所增加。对于专业和业余运动员而言，适当的营养计划对于在这类赛事中取得令人满意的成绩至关重要。目的：确定、评估并将越野跑赛事参与者的碳水化合物、水和钠的摄入量与当前科学建议进行比较。方法：运动员参加的比赛是“2019年阿尔科伊半程越野赛”（西班牙阿尔科伊），赛程为30公里。比赛结束后，参与者填写了一份关于他们在赛事期间食物和饮料摄入量的问卷，以及其他关于他们总体营养习惯的问题。符合纳入标准的11名参与者被纳入研究。结果：平均碳水化合物摄入量为14.93克/小时，钠摄入量为146.42毫克/小时，水摄入量为399.73毫升/小时。共有27%的参与者定期咨询营养学家，且没有人在比赛期间报告胃肠道问题。结论：与当前科学建议相比，参与者的碳水化合物和钠摄入量较低；然而，根据建议，水的摄入量是足够的。我们给耐力运动员的建议是咨询专业的营养学家，以在比赛中取得最佳成绩。
