                                Proper carbohydrate loading can improve endurance performance by 2-3% during long events like an Ironman, making the timing of this strategy critical. Starting too late or incorrectly can lead to digestive issues or missed opportunities for maximum glycogen storage. Mastering the 'when' is just as important as the 'what' to ensure you arrive at the starting line fully fueled and ready to perform.
