While gels are easy to carry, some runners prefer to consume carbohydrate drinks, which help to maintain hydration, preventing the need to carry/consume additional drinks, and are often easier on the stomach. Long stages of 200km mean that riders can be riding for around 5-6 hours which means fuelling on the bike is of critical importance to ensure they have sufficient energy to get through these stages without losing any time. I also started using the Beta Fuel chews. The chews come in Orange and Lemon flavours and provide 46g of carbohydrate. In my opinion these are a welcome change, providing a jelly-like texture different to any other SIS product, the lemon flavour being my personal preference. They’re not too chewy and are easy to consume on both the bike and the run, personally my favourite product from the new range! Beta Fuel gels The science states the new ratio is easier to digest but also has lower volume to consume, (if you were to try and match the carbohydrate content from other gels) which adds to this with less volume being better on the GI system!

The combination of maltodextrin and fructose used in SiS Beta Fuel at a ratio of 1:0.8 provides a formula to enhance carbohydrate delivery and utilisation during exercise, whilst minimising gastrointestinal issues.

The Feed Station

The new enhanced Beta Fuel formula allows you to increase your carbohydrate intake to around 80-120g per hour as a result of the optimised 1:0.8 maltodextrin and fructose ratio. This will aid your performance by minimising gastrointestinal distress and enabling faster absorption.

I always carry 2 bottles on my rides 1 x Electrolyte, and 1 Energy. Very content with these products that I have used some 14 years” – Hugo 10/02/2022 Practically you can carry two bottles on your bike, one bottle to sip at before the race and then one kept in transition to have between disciplines. You could also further increase your intake with a gel before the start of the swim. For the INEOS Grenadiers, SiS BETA Fuel has long been a gamechanger. Originally launched in 2018, it famously powered Chris Froome’s sensational 80km solo ride on Stage 19 of the 2018 Giro d’Italia. It may take time for your body to adjust to high amounts of carbohydrate, this should be done gradually during training, never try anything new on race day! By using a precise balance of maltodextrin and fructose, rather than a single form of carbohydrate, performance improved with Science in Sport Beta Fuel, whilst avoiding any digestion issues. This new range uses a ratio of maltodextrin to fructose at 1:0.8 (previous 2:1) has been proven to:A great way of being able to access nutrition during running is using hydration vests. You can use these vests to carry water mixed with a SiS Beta Fuel Powder, in a flavour of your choice (Red Berry, Strawberry & Lime or Orange). The SiS Beta Fuel Powder also contains sodium which is key for staying hydrated. By using a precise balance of maltodextrin and fructose (1:0.8), rather than a single form of carbohydrate, performance improved with Science in Sport Beta Fuel, whilst avoiding any digestion issues. We have shown that athletes are able to tolerate 120 grams of SiS Beta Fuel per hour, significantly higher than the current recommended intake of 90gms per hour, with no stomach upset. Long been favoured by elite athletes, our famous Science in Sport Beta Fuel Dual Source Energy Drink powder has now been optimised, making it a scientifically superior fuel. A brand new 1:0.8 ratio of 80g carbohydrate enhances your power output, increases your body's carbohydrate usage efficiency, and limits gastrointestinal discomfort It is suggested that during endurance exercise (more than 2.5 hours) 80–120 g of carbohydrate per hour should be consumed to maintain blood glucose levels and prevent fatigue.
