Best suited to endurance athletes who need a simple, high-carbohydrate drink for rides, races or training sessions lasting more than two hours.
SIS BETA Fuel 80 is a dual-source carbohydrate drink powder for long rides, races and endurance sessions. Each 82 g orange sachet provides 80 g of carbohydrate from maltodextrin and fructose, using a 1:0.8 ratio to support high-carbohydrate fuelling when your session runs beyond two hours.
Simply tip one sachet into 600 ml of water and shake thoroughly to dissolve. The isotonic, neutral-pH formula is designed to deliver carbohydrate while minimising the risk of gastrointestinal discomfort, making it practical to sip steadily during demanding efforts. For best results, use one sachet per hour and practise your fuelling plan in training.
This 15-pack is a straightforward choice for riders preparing for long-distance events, stage races or extended training blocks. You can also combine the drink with BETA Fuel Gels or Chew Bars when you want to build towards 80–120 g of carbohydrate per hour or vary your fuelling format.
