GU review
Love MOST of the flavors and they seem to do a good job of "picking me up" later during a ride - about 3+ hours. Salted watermelon and sour peach are 2 of my faves - espresso a close 2nd!!

Great product!
Was weary about using these since some say it upsets their gut, but for me it was perfectly fine. And I love being able to mix and match flavors so I have a different flavor gel every 30 mins. Chocolate, espresso and watermelon are the best imo

GU is a GO
Gels work well in my training regimen. GU is one of my favorites to keep fueled for long rides.
