Sustained energy for long efforts - thanks to optimised maltodextrin-to-fructose ratio
A 1 to 0.8 maltodextrin to fructose split combines two carbohydrate sources to use multiple absorption pathways, aiming to increase carbohydrate uptake and efficiency. The formulation is tuned to deliver 40g of carbohydrates in each 60ml serving.
Fewer mid-session top-ups are typically required, helping maintain power output over extended runs while reducing the chance of energy dips.
Easier digestion while active - with isotonic formulation
Isotonic gels match the body's fluid concentration so the gel can be swallowed without a mandatory fluid bolus, helping contents transit the stomach more quickly. The labelling emphasises minimal risk of gastrointestinal discomfort.
Swallow on the move without needing to chase with water, reducing interruptions to pace and decreasing stomach trouble for sensitive athletes.
Practical, race-ready packaging - with single-use 60ml sachets
Individual 60ml packs are designed for single use, featuring a tear-off top for immediate access and controlled dispensing. Each pouch contains the full 40g carbohydrate portion.
Clear portioning removes guesswork, keeps kit tidy, and makes fuelling strategy simpler during training and competition.
