Carbohydrates are the primary energy source for endurance athletes. They allow for sustained energy release during prolonged physical activity, making them critical for performance. Consuming adequate carbohydrates helps replenish glycogen stores in muscles and the liver, aiding recovery and prolonging endurance capabilities. While fats can also be utilized for energy in longer events, carbohydrates provide readily accessible energy that is essential for high-intensity efforts. Maintaining adequate carb intake is vital for optimal performance and recovery in endurance sports.
