Both GU Energy Gel and our new Roctane Ultra Endurance Energy Gel pack 100 calories into every packet. 100 calories is an ideal serving size to suck down 15 minutes before training or racing in order to top off your electrolyte and glucose stores, followed by one every 30-45 minutes along the way, washed down with a few sips of fluid.

For optimum results, always drink at least 24-30 ounces of fluid per hour during training and racing. Exact GU intake depends on the intensity of your pursuit and your body weight and fitness level. The fitter you are and the more efficient your metabolism, the more GU you can eat each hour, up to approximately 340 calories every 60 minutes.

Combine GU with Roctane Ultra Endurance Gel, GU Electrolyte Brew and GU Recovery Brew for the ultimate in sports hydration, fueling and recovery. Take one gel 15 minutes before training or competition and then one gel every 30-45 minutes during exercise. Drink Electrolyte Brew throughout your training or racing, and drink Recovery Brew within 30 minutes after you’ve stopped.
