GU Roctane Ultra Endurance energy drink powder

Our review

A tasty, energy-filled drink that worked brilliantly. Expensive if used on a regular basis

This powder-based drink from GU is caffeinated, carbohydrate-rich and tasty – pretty much all you need for endurance races. 


Each two-scoop serving (around 600ml) provides 59g of carbs, which are split between simple and complex sugars, as well as sodium, potassium, caffeine, taurine, amino acids and beta alanine. 

Designed to be taken in conjunction with GU Gels, the Roctane drink was delicious during long or hard efforts. The tropical fruit flavour was neither too sweet nor bland, and the caffeine wasn’t overpowering either, making it a real contender for your energy powder needs. 

At £2.92 per serving, it’s expensive if used every day.
