I use these when running half marathons! I alternate between caffeinated and non caffeinated gu’s and that seems to do the trick for me! I’ve use these for 3 half marathons now and they will continue to be my go-to’s!! Easy to carry in a runners belt and easy to tear & consume when running.

This product certainly packs a punch and does so in caffeine free options. There are loads of flavors to try as well but I can see that the texture can be off putting for some. Overall, this product is a great addition to any long workout.

I absolutely love Gu gels for half marathon training. They’re easy to take down, I can definitely feel the difference in energy, and they don’t upset my stomach. Some flavors are significantly better than others, but that’s all personal preference.
