Is the SiS Beta Fuel Gel the right choice for long endurance efforts?

The SiS Beta Fuel Gel delivers 40g of dual-source carbohydrates in a single 60ml gel, built specifically for endurance athletes who need to sustain 80 to 120g of carbohydrate intake per hour during efforts lasting two hours or more. The formula uses a scientifically optimized 1:0.8 ratio of maltodextrin to fructose, which increases carbohydrate oxidation efficiency to 74% compared to 62% with a single-source formula. In practical terms, that means your body can actually use more of what you take in, with significantly less GI distress. Science in Sport developed Beta Fuel in partnership with elite endurance programs including the INEOS Grenadiers.

Each gel is isotonic, ready to consume without additional water, and comes in two flavors: Neutral and Orange. The Neutral flavor is particularly useful for long events where flavor fatigue becomes a factor. Use one gel every 20 to 30 minutes during sustained efforts, combining with other products in the Beta Fuel range: drink mix and chews, to hit the 80 to 120g per hour target without relying on a single format. Informed Sport certified, with every batch independently tested against the WADA banned substances list.
