This makes Beta Fuel one of the most trusted choices for marathon nutrition in Australia. Marathon Nutrition: Why Carbohydrates Matter For endurance nutrition in marathons and ultra-distance events, fuelling correctly can be the difference between a strong finish and hitting the wall. For runs over 2–2.5 hours, experts recommend 80–120g of carbohydrate per hour to: Maintain blood glucose levels for steady energy Delay muscle fatigue so you can push harder for longer Preserve glycogen stores for late-race power Support mental focus and decision-making during critical race moments Pairing carbohydrates with proper running hydration is essential. Dehydration increases the risk of gastrointestinal distress, which is why Beta Fuel electrolyte powder helps you stay fuelled and hydrated without discomfort. How to Use SiS Beta Fuel Powder, Energy Gels & Chews The Beta Fuel range offers flexible fuelling options to suit every runner’s preference: SiS Beta Fuel Powder – Available in Red Berry, Strawberry & Lime, and Orange flavours. Mix with water in a hydration vest or handheld bottle for long training runs. Each serving also contains sodium for optimal electrolyte balance. SiS Beta Fuel Energy Gels – Quick, easy, and fast-absorbing carbohydrate delivery — ideal for race day or high-intensity efforts. SiS Beta Fuel Sports Chews – For runners who prefer a chewable option that feels more like solid food while still delivering rapid fuel. SiS Beta Fuel with Nootropics for Mental & Physical Performance For the final push in a marathon, the SiS Beta Fuel Gel with Nootropics is designed to fuel both body and mind: 40g carbohydrate for sustained energy 1g L-taurine to support endurance 250mg Cognizin® for mental clarity and decision-making 200mg caffeine + 200mg L-theanine for smooth, jitter-free alertness Perfect for the last 10–15km of a race when fatigue sets in and focus is critical. Training Your Gut: The Key to Race-Day Success Every athlete’s digestive system responds differently to fuel. Your ideal running nutrition plan depends on body weight, pace, race distance, and personal preferences for texture (liquid vs. solid). Practise using energy gels, sports chews, and electrolyte powder in training so race day is about execution, not experimentation.

FAQ – Science in Sport Beta Fuel & Endurance Nutrition What is Science in Sport Beta Fuel? Science in Sport Beta Fuel is a high-performance endurance nutrition range designed for marathon runners, ultra-distance athletes, and cyclists. It uses a scientifically proven 1:0.8 maltodextrin-to-fructose ratio to maximise carbohydrate absorption, sustain energy, and reduce stomach discomfort during long events. How much carbohydrate should I take during a marathon? For marathon nutrition, experts recommend 80–120g of carbohydrates per hour during runs longer than 2–2.5 hours. SiS Beta Fuel energy gels, chews, and electrolyte powder make it easy to reach this target without overloading your stomach. What makes SiS Beta Fuel different from other energy gels? Unlike standard running energy gels, Beta Fuel delivers a higher carbohydrate intake with a balanced dual-carb formula (maltodextrin + fructose). This improves energy efficiency, boosts sprint power, and helps you avoid “hitting the wall” in long races. When should I use SiS Beta Fuel Gel with Nootropics? The Beta Fuel Nootropics Gel is best used in the last 10–15km of a marathon or ultra. It combines 40g carbs with caffeine, L-theanine, L-taurine, and Cognizin® to improve mental clarity and focus while sustaining energy levels. Can I use Beta Fuel for training runs? Yes — training with energy gels, sports chews, and electrolyte powder helps you “train your gut” so your body can handle higher carb intake on race day. Practising your fuelling strategy in training reduces the risk of stomach discomfort. Where can I buy Science in Sport Beta Fuel in Australia? You can buy the full SiS Beta Fuel range — including powder, gels, chews, and Nootropics — directly from BikeChain, with free shipping on orders over $100 Australia-wide.
