As discussed in goal two, Cyclocross utilizes all of the body’s energy systems including the ATP-PC, glycolytic, and oxidative systems. A majority of the power output in Cyclocross is generated from glycolysis. This includes both anaerobic and aerobic glycolysis where glucose is converted to ATP for the body’s energy needs. Figure three shows how efforts ranging from thirty to ninety percent of a riders max power will utilize the glycolytic energy system. The glycolytic system is dependent entirely on the presence of glucose in the body. The most abundant form of glucose in the body is its storage form of glycogen. Glycogen is stored both in the liver and directly in muscle tissue. The body’s external source of glucose comes from the consumption
