GU

Launched in 1991, the world’s first energy gel is still the most efficient sports fuel available today. GU’s patented carbohydrate blend delivers high-quality, easily-digested and long-lasting energy for athletes in every sport and at all levels. GU's Berkeley-based sports nutrition company started with original GU Energy Gel, a revolutionary and more effective method to keep athletes fueled during exercise and speed their recovery from exertion. Today thousands of elite athletes and millions of endurance enthusiasts around the world agree: GU works.

Energize
A shot of fast-acting natural fructose (fruit sugar) goes straight to work building your energy levels back up while the maltodextrin is quickly absorbed and sent to your muscles. Vital electrolytes keep your blood chemistry in line and hydration levels stable. Calcium keeps your muscles humming and caffeine adds an extra kick to your power.

GU Energy Gel packs 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.

GU Fueling Instructions

 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.
