The Science in Sport BETA Fuel 80 Drink Mix is a high-carbohydrate powder for long endurance sessions and races where substantial fuelling is required. Each serving delivers 80 g of carbohydrate from maltodextrin and fructose in a 1:0.8 ratio. Science in Sport positions it for sessions longer than two hours and says it forms an isotonic drink when mixed with water.
For the 15-pack powder, mix one 82 g sachet with about 600 mL (20 fl oz) of water. The drink is intended to contribute to a planned carbohydrate strategy rather than replace ordinary hydration by itself. Runners should account for carbohydrates taken from gels, chews and food, and practise the full intake during training before race day. Individual tolerance varies, particularly at high hourly carbohydrate targets.
This catalogue entry groups flavours and pack-size variants under the same BETA Fuel 80 drink-mix model; BETA Fuel gels and chews are separate products. The US$57.99 price reflects the regular official US list price for the 15-sachet pack checked on 23 October 2026.
