Maurten Gel 100 Caf 100
Great taste and gentle on the stomach

After I unfortunately tried other gels (United, Amino Saurus) from RDRC and Key Power Sports, they always go out of stock at the worst possible time. Worse, these companies also have no communication or visibility to runners to help them plan their nutrition for the season.

Simply Active is simply better, and the Maurten gels are great tasting. They are a bit more “solid” than other gels, so you should practice taking them at race pace.
