SIS Beta Fuel 80 is a dual-source energy drink powder designed for prolonged endurance exercise. Each single-serve sachet provides 80 g of carbohydrate from maltodextrin and fructose in a 1:0.8 ratio, giving you a practical way to carry substantial carbohydrate in drink form rather than relying solely on gels or solid food.
Add one sachet to 600 ml of water, shake until dissolved and sip little and often throughout your session. The isotonic, neutral-pH formula is designed to support carbohydrate delivery, while the 1:0.8 blend has been associated with greater carbohydrate oxidation and less reported stomach fullness than a traditional 2:1 blend. It is a convenient option for riders who prefer drinking their fuel and want a clearly measured serving each hour.
One sachet per hour supplies the base 80 g target; add SIS Beta Fuel gels or Chew Bars if you are aiming towards 80–120 g of carbohydrate per hour. The drink contains no salt, so plan your sodium and electrolyte intake separately for longer or hotter rides. The powder is Informed Sport certified, and the strawberry-and-lime flavour gives the mix a distinct fruit flavour rather than a completely neutral taste.
Ideal for endurance cyclists, triathletes and event-focused riders who need a measured high-carbohydrate drink for sessions lasting more than two hours.
