Why There Are Two Fuel Systems
Endurance athletes have different fueling and hydration needs depending on the intensity and duration of their effort. GU developed Original Energy products to provide reliable carbohydrate fuel for everyday training and racing.
Roctane products were created for athletes pushing harder or going longer. In addition to carbohydrates, Roctane formulas include additional electrolytes and amino acids to support demanding efforts where hydration balance and muscle fatigue become greater concerns.
Together, these two systems help athletes match their nutrition to the intensity of their training and racing.
