e-Gel has helped my training for my first marathon tremendously. The e-Gel really takes care of the fatigue I was feeling when I was hitting the 15 mile mark. Now, I can cruise right through it. Also, I would like to say I am glad that Crank Sports has kept any type of artificial sweetener out of their products. Sucralose and Aspartame shouldn’t be in our systems that we push to the limit.
