GU Roctane Ultra Endurance Energy Drink

Roctane Energy Drink is a carbohydrate intensive energy drink for ultra distance and intense efforts, it was formulated for the demands of prolonged, ultra-endurance exercise and specifically, events lasting 4+ hours.

It contains the critical carbs and electrolyte replenishment that endurance athletes need to compete at high levels. And it comes in a super light tasting, easy to mix formula for fueling serious efforts. It also contains caffeine, taurine, and beta-alanine to help increase performance. There’s a lot in there for days when a lot’s going on…

Each serving contains 240 calories of complex and simple carbs that is optimized for rapid absorption and energy accessibility. Key electrolytes such as sodium and potassium help with hydration. Here’s a breakdown of Roctane Energy Drink’s other key performance ingredients:

  • Ideal carbohydrate ratio - Unique ratio of glucose and fructose are podium-proven to better maintain glycogen levels than glucose or fructose alone
  • Key electrolytes - Sodium and potassium properly maintain hydration
  • Taurine - Can help maintain heart & muscle performance during prolonged exercise which would otherwise lead to fatigue and decreased performance
  • Caffeine (except grape flavor) - Can stimulate the central nervous system and reduce pain perception leading to prolonged exercise, delayed fatigue and increased performance
  • Beta-Alanine - Supplements dietary beta-alanine to improve muscle buffering capacity and performance during intense efforts
  • Branch Chain Amino Acids (Leucine, Valine, Isoleucine) – Shown to serve as an additional fuel source (when taken with carbohydrates), reduce muscle damage, enhance recovery and delay fatigue – all critical during intense or long efforts
  • Histidine Amino Acid – helps to promote buffer capacity of muscles

This canister will make 12 servings when mixed as directed.

Recommended Usage

If you already use Roctane gel, you can substitute some Roctane gel for Roctane energy drink. This will help tailor energy intake to your needs and provide the beneficial ingredients found in both the gel and drink.  While many ingredients are similar in the two products (carbohydrates, branched chain amino acids, histidine, and caffeine) each has unique ingredients which may also help improve performance (gel – OKG for muscle recovery, vitamin E as an antioxidant; drink – taurine to help heart and muscle function, beta-alanine to help increase muscle buffering capacity). Therefore, using both products will help provide every nutritional advantage possible to athletes who demand the best from themselves and their nutrition. For many athletes, all they may need during prolonged exercise is one 21oz bottle of Roctane drink and 1 Roctane gel per hour for 340 calories and extra nutritional support to maximize performance


GU Roctane Energy Drink is available in Lemon & Lime or Tropical Fruit flavours.

Press Reviews

Triathlon Plus

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 everyday. Verdict - A tasty energy-filled drink that worked brilliantly. Expensive if used regulary.
