Review: Best gels I’ve used. - Easy to eat on the bike and is like rocket fuel - gives you a great energy boost. I was 50 miles into a 70 mile ride and didn’t fuel properly. I hit the wall completely a friend handed me one of his And within 20 mins I was back to the front of the group. It was amazing. I’ll never use anything else again. Texture not too thick and not too thin. These are highly effective energy gels. I also used on my most recent half marathon and it was brilliant to use every 30mins due to the carbs. Loved them.
Review: Caffeine works well - taste is ok - Like the beta fuel gels. These have a good hit of caffeine which certainly helps on very long runs. These caffeine gels don’t taste as nice as the normal ones, but you get used to it as you look forward to the hit!
