Glycogen Meaning in Cycling

Glycogen is the primary form of energy stored in your muscles and liver for high-intensity exercise. When you cycle hard, your body breaks down this glycogen to power your legs. You only have a limited supply of it, which usually lasts for about ninety minutes to two hours of hard effort. If you run out of glycogen completely, you will experience “bonking” or hitting the wall. To keep your glycogen levels up, you must eat carbohydrates like gels or bars during your ride. Proper recovery after a ride also involves eating to refill these vital energy stores for the next day. For example, a racer eats a large pasta dinner the night before a big event to maximize their glycogen stores. This ensures they have enough fuel to compete at a high level without running out of energy. It is the fuel tank of your body.
