Maintain performance during training, with a high proportion of carbohydrates

High carbohydrate content is concentrated into a 60 ml isotonic gel, designed so carbohydrates are available for rapid uptake during activity. The isotonic balance reduces the need for extra water to aid absorption.

Provides quick fuel to help sustain pace and intensity during long runs or cycles, while limiting stomach heaviness.

Support fluid balance, with added sodium plus magnesium and calcium

Electrolyte mix includes sodium to aid hydration and minerals such as magnesium and calcium that are lost through sweat. The isotonic format helps electrolytes remain in solution for easier uptake.

Helps replace electrolytes lost during sweating, assisting hydration and reducing the likelihood of cramps on prolonged sessions.

Gentle on the stomach, with an isotonic, easy-to-digest texture

Formulated to be isotonic so the concentration matches body fluids, lowering digestive strain. User feedback highlights a smooth texture that passes easily during exertion.

Smooth texture and isotonic balance make mid-ride or mid-run refuelling less likely to cause nausea, suitable for athletes who struggle with thicker gels.
