UCI Sports Nutrition Project: Competition and Training Demands, Physical Characteristics, and Nutritional Strategies for Performance in Bicycle Motorcross Race.

Bicycle motorcross racing is a unique sprint cycling discipline that takes place on a 300- to 450-m outdoor track with an 8-m start hill. A single race is 30-40 s in duration, and athletes can compete in up to seven races per day. Athletes require highly specific physiological attributes to meet the training and competition demands, and successful riders can produce high peak power outputs and demonstrate technical and tactical superiority over their opponents. Nutrition has a key role in optimizing athlete health, training adaptations, and overall athlete performance. This review will focus on the training and race demands for bicycle motorcross race and fueling strategies to support training and racing outcomes.
