The new SiS Beta Fuel powder solution will contain 80g of carbohydrate at this 1:0.8 ratio, in a neutral pH formula still maintaining the signature isotonic format to minimise gastrointestinal issues. The Beta Fuel range has little or no electrolyte content, so this should be considered separately. See the SIS GO Hydro tablets or GO Electrolyte powder for electrolyte focused products.

In summary, the Science in Sport Beta Fuel range works by providing these two different forms of carbohydrate in a formula which can be simultaneously absorbed. This is key as the transportation of nutrients across the intestinal wall, which is a rate-limiting factor in carbohydrate oxidation during exercise. 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… The longer we run for, the more we need to focus on fuelling strategies. Under fuelling and dehydration will ultimately lead to ‘hitting a wall’, where putting one foot in front of the other suddenly becomes a tremendous task. According to SiS’s CEO Stephen Moon: “We have been able to completely change the game when it comes to fuelling endurance athletes. It’s always been a fine art, but we’ve never been closer to perfection than we are now.”
Frequently Asked Questions
Generally, Wiener recommends consuming 1g of carbs per kilo of bodyweight every 60 minutes. So, if you weigh 80kg, aim for 80g of carbs per hour of exercise.
Unfortunately it's not just as simple as going double strength as this may cause the stomach problems that the Beta Fuel is designed to avoid. I've been using SIS Beta Fuel for the past 10 or so months for road and cyclo-cross racing. It has been fabulous, giving me a noticeable boost in energy during the second half of a race. I've had no stomach issues and it's much easier to use, in my experience, than energy gels. For me, Beta Fuel has been a game changer and one that I'm happy to pay for.

Wallis, G.A., Rowlands, D.S., Shaw, C., Jentjens, R.L., Jeukendrup, A.E. (2005). Oxidation of combined ingestion of maltodextrins and fructose during exercise. Medicine & Science in Sports & Exercise. Mar;37(3):426-32. In short, the all-new Beta Fuel range works by providing two different forms of carbohydrate, maltodextrin and fructose, which can be simultaneously absorbed. This is key as the transportation of nutrients across the intestinal wall is a rate limiting factor in carbohydrate oxidation during exercise. The new formula of Beta Fuel uses an optimised ratio of maltodextrin to fructose at 1:08 (previously 2:1) providing a science-based, complete fuelling solution for triathletes. Science in Sport energy chews deliver 46g of fast carbs in a tasty, convenient gummy bar which enhances output without leaving you feeling full and heavy. Importantly, as mentioned above the 1:0.8 ratio has been shown to reduce symptoms of stomach fullness and nausea when compared to the 2:1 ratio which is great when considering the gastrointestinal issues often reported during running.
The 120g carbohydrate intake can be achieved from our drink, gel or jelly chew, or any combination of the three For a three-hour ride, aiming for 80–120 g of carbohydrate per hour (240-360 grams in total), you could use the SiS Beta Fuel range in the following formats: SiS Beta Fuel Options: I'll start with the nutrition issues that I was having. Put simply, I was struggling to get nutrition onboard in enough volume to sustain the rate that I burn it during a race. Take, for example, one early-season E12 race. The 125km race lasted 3 hours and in that time I burned 2,243 calories. My usual nutrition strategy of two 500ml bottles (189kCal each) of SIS Go Energy and around five High5 Energy Gels (91kCal each) left a deficit not just in calories but also in carbohydrate. This intake gave me 209g of carbs. When considering trying to consume 80-120g of carbohydrate per hour, individuals may take time to adapt to consuming this amount of carbohydrate and the optimal amount per hour may also vary slightly depending on the individuals body weight. It is important to practice your nutrition during training to find the optimal amount that works for you.

Because there’s such a plethora of energy products available, try a few and see how they sit with you. “Once you find something you like, I’d suggest training with it consistently. This will help your body adapt to its usage and lessen the risk of digestive issues at critical moments.” How We Test The Beta Fuel Energy Chew has been scientifically formulated to be a superior fuel in a satisfying chew form. Each chew contains 46g of carbohydrate, with an improved 1: 0.8 ratio of maltodextrin to fructose, which increases the percentage of ingested carbohydrate that is oxidised (known as efficiency). This unique ratio also helps to minimise gastrointestinal discomfort. Without compromising taste or consistency, you can double the amount of carbohydrate in comparison to normal gels which is great on longer distance races when you have limited storage on the bike.
Completing our fuelling solution is the SiS Beta Fuel Chew Bar. We know that during endurance exercise, being able to vary your fuelling choices is important. Within the new SiS Beta Fuel range, we are providing you with even more choice without compromising on quality or taste, meaning you can maintain optimal sources of energy. These chews are in a unique format to SiS, being super easy to consume and available in Orange and Lemon flavours.

In general, as exercise intensity increases, you become more reliant on carbohydrate stored in your liver, blood and muscle. However, your body can only store enough carbohydrate for up to 90-120 minutes of exercise so it’s important to consume adequate carbohydrate during cycling.
