I am been doing a lot of 70-100 mile rides. I used to just drink water, but I have been turned onto these GU packets and shock blocks that they instant give me bursts of energy. I did a century ride event and met this guy who was telling me all about long chain sugars, ect (he used Hammer nutrition). He thought GU was too much sugar. I tried one of his hammer packets and didnt feel as good as I do when I eat a GU 50 miles in. What do you prefer, or do you stick to water as well?
