Product of Cologne List®
Commitment to a Clean Sport

Unlock your performance with the complete ATOM fuelling system in one box.
GEL 30, ISO 30 and BAR 30 each deliver 30 g of carbohydrates, giving you the energy needed to sustain intensity and stay stronger for longer. Their consistent carbohydrate content makes it simple to combine formats, reach a targeted intake of 60–90 g per hour and build a fuelling strategy you can rely on when race day arrives.
With 180 g of carbohydrates in total, the Discovery Box provides enough fuel for approximately two endurance sessions, helping you train your nutrition, maintain energy levels and identify the combination that delivers your best performance.
HYDRA 500 supplies key electrolytes to support effective hydration, replace minerals lost through sweat and help maintain fluid balance before, during and after exercise.
All products are listed on Cologne List® supporting our commitment to clean sport and high-performance nutrition.
