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.

Great before a race.
These are my favourite gel fuels to use especially before a marathon. They taste good and sit well before races.

Great fuel but hard to open
It's double the capacity of most gels so you don't need so many stuffed in your pockets. Like most the taste is a bit sickly-sweet after a couple but did not cause me any nausea or GI problems. Got me through first marathon in good shape! Only problem is opening, obviously you don't want it too easy but you have to twist the top multiple times to get it off, leaving you with a tiny bit of rubbish to try not to drop and a very small opening that you have to squeeze really hard to get anything out. Sometimes this doesn't work and I had to tear at it with my teeth, not something you really want to do while running. Surprised they can't find a way to make this a bit easier to get into when on the move.

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.

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.

First time that I try this Gel
I have nothing to complain about. I tried it during a couple of runs and it worked well for me during my last Hyrox.
