When should you use the SiS Beta Fuel + Electrolyte Gel Box of 30?

The SiS Beta Fuel + Electrolyte Gel Box of 30 is the full-supply format of the Beta Fuel gel built for hot conditions and high-sweat efforts: 40g of dual-source carbohydrates in the 1:0.8 maltodextrin-to-fructose ratio, plus 200mg of sodium per gel for electrolyte replacement during prolonged exercise. Science in Sport developed this gel for athletes who need maximum carbohydrate delivery and meaningful electrolyte support in one product, without having to manage separate gels and electrolyte tablets mid-race. The formula is isotonic and can be consumed without additional water.

Use this gel during training or racing in warm or humid conditions lasting two or more hours, or any time elevated sweat rate demands both fuel and sodium replacement simultaneously. Consume one gel every 20 minutes to deliver up to 120g of carbohydrate per hour alongside consistent sodium intake. Works seamlessly with other products in the Beta Fuel range. Informed Sport certified, every batch tested against the WADA banned substances list. If hot-weather endurance racing is a regular part of your season, this 30-pack covers you.
