BSIM Choose Your Flavors



We are thrilled to be fueling athletes at the first marathon that we ever sponsored back when GU was just getting started!

We wanted to give you runners a chance to choose your GU! Make sure your voice (and belly) is heard by voting for the flavor you want to see at aid stations. 

The flavors listed below are part of our ROCTANE line of products. ROCTANE Energy Gels are different from our original Energy Gels because they pack more amino acids and more electrolytes (sodium) to give your body what it needs when it's going further and harder than ever before. (Caffeine amounts listed in milligrams.) 

By voting, you're agreeing to sign up for our awesome newsletter! (It'll be worth your while... we promise.)
