Race Day Fueling

Understanding the roles of glucose and fructose is crucial for optimal race day performance. While glucose is primarily sourced from common carbohydrates like rice and pasta, fructose is essential for replenishing liver glycogen, especially the morning before a race. Aiming for a 2:1 ratio of glucose to fructose in your pre-race meal can enhance energy stores, ensuring your muscles have the fuel they need during the marathon.
