I used some Red Bull on the Tour De Cure. I liked it. We were 20 miles from the end and riding at a fast pace, I was dying. I was so sick of Chocolate Ravage Gu's that I could puke. Then the Red Bull truck pulled up and handed me an icy cold one, I drank a little of it ful power, and then mixed the rest in a water bottle. I made it to the end, with no more Gu's. I like Red Bull!
