A Powerful Energy Boost for Endurance Athletes
I recently tested Science in Sport Beta Fuel Gels during an ultramarathon, and I was impressed with their effectiveness. Key Features: * Enhanced Power Output: The new ratio of maltodextrin to fructose (1:0.8) provides a balanced source of carbohydrates for sustained energy. * Easy to Consume: The gels have a smooth texture and a pleasant taste, making them easy to consume during exercise. * Gentle on the Stomach: I didn't experience any stomach discomfort while using these gels, even during intense activity. My Experience: I used these gels during a mid-race lull when my energy levels were starting to drop. They provided a noticeable boost, helping me maintain a consistent pace and finish the race strong knocking over an hour off my previous race time. The combination of the beta fuel formula and the balanced carbohydrate content seemed to work well for me. Overall: If you're looking for a reliable and effective energy gel for endurance activities, Science in Sport Beta Fuel Gels are a great option. Their unique formula, easy consumption, and gentle on the stomach properties make them a valuable tool for athletes seeking to optimize their performance.

Perfect
Purchased these for Manchester Marathon 2026. Worked really well as I got a PB of 3:08. Good taste, easy to consume and definitely give you the required energy to compete.

Excellent product
Excellent food on the run. Perfect for use whilst running. Easily digestable with no upset stomach. I regularly run 10 miles and have used these on a 21 mile run, no problems at all.

Went down well
Used them in the middle of a long run and felt good. Preferred the orange flavour but still palatable which is better than many on the market

Strong sweet taste, but keeps me training
This is only my second time ordering these 40g Carb jels, I've always used the 20g by SIS prior but with training for longer distance I need more grams per hour. Whilst they're similar in texture to the 20g jels the taste is much more intense, a lot sweeter. If like me you have a sweet tooth you'll be fine. Size wise they're the same as the 20g jel and quality of liquid is the same too, really good. They're a simple and easy to use tear off the top then squeeze like a toothpaste tube. I found they help me last well and get to my grams per hour goal. They are expensive but worth the value. I don't have any issues with my stomach on these either.

Endurance training fuel
Take these every 30-40 mins on long runs. Great size, fit into pockets and vests easily, and gives me the boost I need to finish training on a high.

Great gels
Much prefer to runnier gels tried previously. Flavour is decent. Carb make up is perfect for energy. Top tip for all gels is to sip them over a couple of km before a water station and then take on water to wash them down. Plan on using a mix of these and sis chews for a marathon. Find strength of these means theyโre good value for training with too as one is more than enough to get me through a slow half marathon ish training run.
