When it comes to endurance performance, every gram of carbohydrate counts. Whether you’re tackling an Ironman, ultra-marathon, long cycling session, or a big weekend brick, fuelling correctly can make or break your day. That’s where SiS Beta Fuel Gel comes in — a scientifically formulated endurance gel designed to help you perform stronger, for longer.
The Science of Dual-Carb Fuel
What makes SiS Beta Fuel stand out from the crowd is its unique dual carbohydrate blend. Each gel delivers 40 grams of carbohydrates in a 1:0.8 maltodextrin-to-fructose ratio, allowing your body to absorb and use up to 90 grams of carbs per hour.
Traditional gels use a single carbohydrate source, meaning your gut can only handle so much before things go sideways (hello, stomach issues!). SiS Beta Fuel, however, combines two carbohydrate types that use different transporters in the gut — meaning faster absorption, reduced GI distress, and more available energy to power your performance.
Why Athletes Love SiS Beta Fuel Gel
Endurance athletes swear by SiS Beta Fuel because it ticks all the boxes for performance, convenience, and taste. Here’s why it’s a go-to for elite and everyday athletes alike:
-
🚀 High-Carb Energy Boost: 40g of carbs in one hit to sustain high-intensity efforts.
-
💧 Isotonic Formula: No need to chase with water — easy on the stomach, even late in a race.
-
⚡ Rapid Absorption: Dual-carb blend means quicker energy delivery to working muscles.
-
🧠 Fuel for Body and Mind: Beta Fuel is proven to support both physical and cognitive performance, helping you stay sharp when fatigue sets in.
-
🍋 Great Flavours: Available in options like Lemon & Lime, Strawberry & Lime, and Orange for smooth, non-sickly fuelling.
How to Use SiS Beta Fuel Gel
Fuelling is personal, but here’s a general guide that works well for most endurance athletes:
-
Before Training/Race: Take 1 gel 15–30 minutes before to top up glycogen stores.
-
During: Aim for 1–3 gels per hour depending on your intensity, body size, and other nutrition sources.
-
Hydration: Pair with electrolyte drinks (like Precision Hydration or SiS Hydro) to maintain optimal hydration and sodium balance.
Tip: Practice your fuelling strategy during training, not on race day. The goal is to train your gut to handle higher carb intake efficiently.
The Beta Fuel System
SiS Beta Fuel isn’t just a gel — it’s a complete performance fuelling system. The range includes drink mixes, chews, and gels, all designed to work together so you can hit your personal carbohydrate targets in whatever form works best for you.
This gives you the flexibility to mix and match — perhaps starting your session with the drink mix, then switching to gels or chews as your session intensifies.
The Bottom Line
If you’re serious about endurance performance, SiS Beta Fuel Gel is one of the most scientifically advanced and athlete-approved options on the market. It delivers big carbs, easy digestion, and reliable energy when you need it most.
At Training House Shop, we love Beta Fuel because it helps our athletes train smarter, race stronger, and recover faster — no bonks, no GI distress, just pure performance.
