Created for high-intensity and demanding activity, GU Roctane Energy Drink Mix packs even more electrolytes and carbohydrates than GU Hydration Drink Mix. The 250-calorie serving contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. Sodium, the primary electrolyte lost in sweat, aids hydration by maintaining water balance. The amino acid taurine helps maintain heart contractility and improve cardiac output during long exercise sessions, while the amino acid beta-alanine helps promote formation of the intramuscular buffer carnosine.

Grape flavour contains no caffeine.

The Drink of Champions

I won my 100km this summer using this as my primary nutrition source backed up with gels. No stomach issues at all. Don't take my word for it, Magda Boulet won 2015 Western States 100 miler doing just the same.
