FAQ

Why does the 1:0.8 carb ratio matter?

Glucose and fructose use separate transporters in the small intestine. By combining them at the right ratio, the gut can absorb up to 90g of carbohydrates per hour rather than the 60g ceiling you hit with glucose alone. For long, hard efforts this means more fuel available to working muscles.

Is Beta Fuel appropriate for shorter rides?

At 40g per gel it is most effective for efforts over 2 hours where high carb delivery is a priority. For shorter training rides, GO Isotonic at 22g per gel is more appropriate and easier on the gut when total intake is lower.

How many Beta Fuel gels can I take per hour?

Two Beta Fuel gels per hour delivers 80g of carbohydrates, near the upper end of what well-trained athletes absorb comfortably. Gut training is important here. Practice with Beta Fuel in training before using it in a race.

Best For

Road racers, gran fondo riders, and triathletes who need maximum carbohydrate delivery across multi-hour efforts. The go-to gel when fueling volume and absorption rate are the limiting factor in performance.
