Best gels I've ever tried
Beta gels are excellent for any activity lasting more than an hour. I practice road and trail running, and the fact that they have double the carbohydrates compared to conventional gels makes a difference. They have a very good consistency in the mouth and are easy to swallow durung your activity with a minimum requirement of water. Highly recommended.

Give a good energy boost when you need it most. Tastes a bit like calpol (acquired taste) in my opinion and quite thick compared to other gels

Heavy on the carbs, but also your stomach.
Positives: Science in Sport Beta Fuel Gels deliver a substantial energy boost, thanks to their higher calorie and carbohydrate content compared to the original gels. This makes them particularly effective for sustaining energy during long runs. The orange flavor is a notable improvement over the original non-beta version. The Beta Gel's sour orange taste is refreshing and much more palatable, avoiding the overly sweet profile that can be off-putting during intense exercise. Negatives: However, these benefits come at a cost. The Beta Fuel Gels are significantly more expensive than the non-beta version, which might make regular use less feasible for some athletes. Additionally, the Beta Gels weigh considerably more, adding to the load you're carrying during long runs. They are also much thicker and harder to swallow, which can be a real issue if, like me, you run half marathons without water. Unlike the originals, these gels don't relieve a dry throat, making them less ideal for hydration management during prolonged runs. This extra weight, combined with their heavy consistency, can be tough on the stomach. I've experienced an urgent need for the toilet during runs with the Beta Gel, an issue I never had with the original non-beta version. Overall, Science in Sport Beta Fuel Gels provide an effective and tasty energy boost, but their higher cost, increased weight, thicker consistency, and potential for digestive discomfort may be drawbacks for some users. If you can handle the downsides, they are a strong option for endurance athletes looking for that extra push

Performance + Taste.. absolute winner!
Having been an endurance athlete for many years, focusing on hybrid races more recently including Hyrox. These are a step above with it's taste and performance. The gel is smooth and consistent. The rip off is easy, even running at pace. You can feel the surge of energy post consumption. I historically have stomach issues but these seem to be fine. Taking 4 over the duration of a half marathon no problems. They aren't the cheapest out there but pound for pound you don't want to go cheap for performance gains!

Really helped me out these

I like the taste of these gels and they are very effective in maintaining my energy level during a marathon. In addition to maintaining the carb level, there's some electrolytes in the content as well. With these gels they are like drinking liquids which allows for easy abortion and can be taken without water.
