When you’re pushing through a long run, bike ride, or any endurance workout, your body needs consistent energy to perform at its best. That’s exactly what the SiS Beta Fuel Energy Gel delivers.

With 40g of carbohydrates in each gel, it provides a fast-acting, sustained energy source that helps keep you going for the long haul.

What I really like about this gel is the combination of maltodextrin and fructose. This dual-source carbohydrate blend ensures that your body can absorb and utilise the energy more efficiently, giving you that steady boost without the sugar crashes.

The gel format is convenient, making it easy to consume during your workout or race, and you don’t have to slow down to drink or carry extra gear.

Who it’s for:

Endurance athletes (runners, cyclists, triathletes) needing fast, efficient fuel during sessions – especially when you need to stack 3–4 gels per hour for long efforts.

What it does:

Delivers 40g of fast-absorbing carbs in a dual-carb mix proven to maximise oxidation. The low-acid formula keeps your stomach happy and helps you keep pushing hard.

How I’d use it:

Take one gel every 30 minutes during racing or training, always sip water alongside to support absorption. Works well combined with drinks or chews for higher hourly carb needs.

The Science:

Substrate Utilisation and Exercise Capacity with Solid, Gel, and Drink Fuel Formats

Study: A randomised crossover trial comparing equal carbohydrate intake (80g/h) via drink, gel, bar, and a mixture, assessing performance, carbohydrate oxidation, and gut comfort in trained cyclists.

There was no clear performance difference between gels, drinks, and mixed formats, but gels offered significantly better gut tolerance and slightly higher peak power vs bars – supporting the performance comfort of gel formats like Beta Fuel.

Multiple-Transportable Carbohydrate Ingestion Improves Competition Performance

Study: Randomised controlled trial within actual half-Ironman races comparing a traditional glucose-only fuel strategy vs a mixed (maltodextrin-glucose/fructose) strategy across gels, drinks, and bars averaging 79g/h.

Athletes using mixed multiple-transportable carbs achieved small but meaningful performance gains in triathlon races, with high compliance and no increase in gastrointestinal complaints versus glucose-only fuelling – validating Beta Fuel’s 1:0.8 approach for race-ready athletes.
