Endurance athletes, especially those following a plant-based diet, should prioritize nutrition the night before intense training sessions. Proper fueling is crucial for performance, as it can significantly impact energy levels and reduce gastrointestinal issues during workouts. Key recommendations include increasing carbohydrate intake while avoiding high-fat and high-fiber foods, unless accustomed. It’s advised to select lower-fiber vegetables and ensure meals are appropriately seasoned, especially in warmer climates. Seeking guidance from a sports dietitian can further enhance pre-training nutrition strategies.
