So as runners, we need to be consuming both adequate carbohydrate whilst also staying hydrated to perform at our best and hopefully avoid gastrointestinal issues. I really like the Beta Fuel chew bar, more for the taste because it’s not a sandwich or rice cake or bar. It’s more enjoyable when you eat it,” says Elia Viviani.

Through our Performance Solutions team, we've worked closely with elite athletes in the research and development of the new Beta Fuel range to bring you a scientifically superior fuel in a range of formats that allow you to use +17% more carbohydrate (O’Brien et al, 2013). Each Science in Sport energy powder comes in a variety of flavours to suit individual preferences, in general we would recommend having a look at GO Energy or GO Electrolyte for exercise less than 2 hours, then would advise starting to look at Beta Fuel for exercise longer than this. As always though, nothing new on race day, make sure you train with any powder you are planning to use on an event! Rowlands, D. S., Thorburn, M. S., Thorp, R. M., Broadbent, S., & Shi, X. (2008).

Science In Sport's Beta Fuel is a carb-dense drink that has changed my race-day nutrition. The taste is good and for most races the 80g of carbs in a 500ml bottle mean that gels aren't needed. It's kind on the stomach too, with no 'tolerance build-up' needed. While the price is on the high side, this is a genuinely brilliant product.

Chris Froome credits his famous 80km solo ride on stage 19 of the 2018 Giro D’Italia as his greatest feat on a bike. It’s unsurprising. Many inside the cycling world consider it one of the most sensational days in Grand Tour history. I have been testing out the new range of BETA Fuel energy products from UK brand Science in Sport. They are tasty, easy to take onboard, and a notable scientific development over their predecessors and many other energy products on the market. Here's the low-down…

Remember, as a runner, you are still an individual. Both in preferences of fuel (i.e., liquid, or solid) and how much carbohydrate your body needs depending on body weight. The new SiS Beta Fuel range is leading a revolution in endurance fuelling. Already a favourite of INEOS Grenadiers, the team has been instrumental in testing and developing the new formula since 2020, fuelling Tao Geoghegan Hart to his first Grand Tour victory in the Giro that year. The new range of Beta Fuel products has an optimised ratio of maltodextrin to fructose. Our previous version used a ratio of 2:1, whilst the new range is 1:0.8.

As an endurance athlete our Beta Fuel Dual Source Energy Gel can be used on its own to fulfil your fuelling requirements. However, the SiS Beta Fuel range, which also includes the Dual Source Energy Gel + Nootropics, the Dual Source Energy Drink, and Dual Source Energy Chew Bar, can be combined to ensure you easily hit the recommended fuelling target of 80-120 grams of carbohydrate every hour. One sachet of Beta Fuel Energy Drink contains one serving (82g) of powder. Tip the mix-and-go formula into 600ml of water and shake to dissolve. Sip little and often during prolonged endurance exercise. Use one powder sachet per hour. Many energy supplements promise big, deliver little and come with temporary but distracting side effects, which can be all-consuming for a cyclist in the saddle. Whatever Morton and his team conceived, it had to be isotonic with a neutral pH to increase the ability to digest it and absorb the carbohydrate with minimal feelings of gastrointestinal discomfort. The right combination of nutrition for running is a common challenge for most. As a runner, we have all been there, when your stomach starts churning you cannot focus on enjoying your run whether this is during training or a race. Fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use.Relaunched in June of 2021, it now has a brand new optimised 1:0.8 ratio of maltodextrin to fructose, that when compared to traditional 2:1 ratio, is proven to enhance power output, increase carbohydrate oxidation efficiency, and limits gastrointestinal discomfort. It was some task, but around February of 2018 SiS Beta Fuel was created and trialled at warm-up races and training camps in readiness for use by Team Sky riders at that year’s Giro. Energy powders and drinks are just one of many formats available at Science in Sport, from GO Energy Bakes to GO Energy Bars and GO Isotonic Energy Gels to Beta Fuel Chews. Part of an entire world-leading fuelling solution range that includes drinks and chews, our Beta Fuel Dual Source Energy Gel is optimised with a brand new 1:0.8 ratio of 40g carbohydrate to enhance your power output, increase your body's carbohydrate usage efficiency, and limit gastrointestinal discomfort to deliver a scientifically superior fuel. Fuelling some of the world’s best riders in one of the world’s most successful teams in professional cycling is no easy task. But Science in Sport continues to do just that, satisfying its riders with world-leading nutritional products.

In the first study of its kind, we tested feeding athletes 120g of Science in Sport Beta Fuel per hour, singularly, and combined across our patented range of gels, chews and drinks. The previously recommended intake for endurance fuelling was 90g per hour. O’Brien, W. J., & Rowlands, D. S. (2011). Fructose-maltodextrin ratio in a carbohydrate-electrolyte solution differentially affects exogenous carbohydrate oxidation rate, gut comfort, and performance. American Journal of Physiology-Gastrointestinal and Liver Physiology, 300(1), G181-G189. SiS says that optimum fuelling is between 80-120g of carbs per hour, but from personal experience I'd say most people will require a fair bit of practice to take the upper end of that without stomach discomfort. My personal preference is about 90g per hour, which can easily be achieved with a single Beta Fuel gel and a bottle of decent energy drink. Energy Drink Powder – 80g carbohydrate with neutral pH and isotonic formulation to minimise GI distress The new SiS Beta Fuel Powder solution contains 80 grams of carbohydrate at this 1:0.8 ratio, in a neutral pH formula still maintaining the signature isotonic format to minimise gastrointestinal issues. The Powder is available in Orange, Strawberry and Lime and Red Berry flavours.

For those who like to consume gels whilst running, the SiS Beta Fuel Gel with Nootropics could be a game changer during that last push. Ideal for when you are in the last quarter of your marathon, you know the end is near, it is all going to be worth it, but your physically and mentally exhausted and in need of a boost to help give you that push to the finish. The Science in Sport Beta Fuel range provides a variety of performance solutions to choose from to build your ultimate nutrition strategy. You might already have used our SiS Beta Fuel Powder, so other than having new SiS Beta Fuel options in Gels and Chews, what is different about it? Great for endurance athletes that are trying to go the distance. The Beta Fuel 80 delivers an optimised 80g of carbohydrate in a single, convenient isotonic fuelling solution with minimal risk of GI discomfort. Lemon: Sugar, Water, Glucose Syrup, Fructose Syrup, Gelling Agent (Pectin), Flavouring, Acidity Regulator (Citric Acid), Corn Starch, Glazing Agent (Coconut Oil, Carnauba Wax), Colour (Turmeric Extract). In the first study of its kind, we tested feeding athletes 120g of Science in Sport Beta Fuel per hour, singularly, and combined across our patented range of gels, chews and drinks. The previously recommended intake for endurance fuelling was 90g per hour. These results have never been seen before and change everything we thought we knew about endurance fuelling guidelines, and the performance potential in elite endurance racing:
