Interventions
Dietary intake and three questionnaires will be used:Dietary intake will be assessed with 3 day food record using the Traqq app developed by Wageningen University. Based upon the individual’s training
(Trakman et al., 2018) offers a validated method to assess sport-specific nutrition knowledge, including understanding of macronutrient requirements and fuelling strategies)The LEAF/LEAM-Q  
(The Low Energy Availability in Females Questionnaire (LEAF-Q) 
(Melin et al., 2014) and the Low Energy Availability in Males Questionnaire (LEAM-Q) 
(Lundy et al., 2022) are screening tools and provide practical approaches for identifying athletes at risk of LEA in field-based settings)A general questionnaire to obtain demographics, exercise habit

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Daily Carbohydrate IntakeAssessed via a 3-day dietary record using the Traqq app.This outcome provides quantitative insight into the average daily carbohydrate consumption of trained distance runners, contextualized according to individual training load, allowing evaluation of whether carbohydrate intake meets the demands of endurance training.Nutrition KnowledgeAssessed using the Abridged Nutrition for Sport Knowledge Questionnaire (ANSKQ).This outcome evaluates sport-specific nutrition knowledge, including understanding of macronutrient requirements, energy fueling strategies, and principles of optimizing dietary intake to support training and performance.Risk of Low Energy Availability (LEA)Assessed using sex-specific questionnaires: the LEAF-Q for female athletes and the LEAM-Q for male athletes.This outcome identifies athletes who may be at risk of low energy availability, a condition that can compromise metabolic, hormonal, bone, and immune function, as well as athletic performance. | — |
