Good stuff
I know that Gu isn’t as popular anymore since the development of the Precision/Maurten gels, but I find them easier to get down. If you mix several gels in your water bottle, you get the necessary water to help you absorb them and it’s a nice change from other gels because there’s so much flavor variety- I’ve gone back to them and am really liking them again.

So good
The chocolate coconut is decadently good. Not loving the cherry limeade as much, but both always give me that pop of energy when I'm gassed.

Love this gel
I love the kiwi starwberry, pinneapple, and cold brew flavors of this gel. They work great for my long runs.
