I have been racing MTB for about 8 years now, but only this past February I did my first 12 hour race. It was an amazing race this was the first long race where I used the e-Gels. They were of great help or I would say of the help, since the e-Gels were the only food I consumed during the 12 hours. I dont know but eventhough I didn’t eat anything else I felt that was one of my strogest races. Thanx Crank Sports.
