I trained for the Adidas Vancouver Marathon using e-Gel, which I found and ordered over the internet. I especially liked the fact that it contained electrolytes since I am not a fan of sports drinks due to the sugary after-taste. My goal was to complete the Marathon, my first, in 3:45:00. I finished in 3:35:37, using e-Gel the entire way. It was also nice to carry less packs than other brand gels due to the larger size. I am hooked on e-Gel and will continue using it during future Marathons. I hope to someday see a chocolate flavor!! Thanks Crank Sports!!
