A strong choice for endurance riders, runners and other athletes planning sessions or events longer than two hours who want 80 g of carbohydrate in a single prepared drink.
SIS BETA FUEL 80 is a convenient energy drink powder for prolonged endurance exercise, particularly sessions lasting more than two hours. Each 82 g sachet delivers 80 g of carbohydrate, giving you a clearly defined fuelling target in a bottle-ready format. The Red Berry flavour adds variety to your on-bike nutrition plan, while the individual sachets make it easy to portion your drink before a long ride, race or training session.
The dual-source formula combines maltodextrin and fructose in a 1:0.8 ratio. This formulation is designed to support a high carbohydrate intake and is intended to reduce feelings of stomach fullness and nausea compared with a 2:1 ratio. The prepared drink is described as an isotonic fuelling solution, giving you a straightforward way to take in carbohydrate while exercising.
To prepare it, add one sachet to 600 ml of water, shake until dissolved and sip little and often. The recommended starting point is one sachet per hour. If your fuelling plan calls for 80–120 g of carbohydrate per hour, combine the drink with SIS BETA FUEL gels or energy chews. With 15 individually portioned sachets in the pack, this is a practical choice for riders who want consistent, easy-to-plan fuelling across a block of long sessions.
