I am 35 years old and completed my third marathon, Top Of Utah. Figuring out how to stay hydrated and prevent muscle cramps during long runs and races has been one of my biggest challenges. In the past my muscles would ache and twitch and cause me a lot of pain after long runs. I tried Gatorade and other carb gels but had a hard time finding something that was easy on stomach, kept me from cramping, and helped me avoid bonking. I came across Crank e-Gel this summer during my training for my most recent marathon. The first time I used it was during an 18-mile training run. I felt great throughout the run and felt like I could have kept running. I was surprised that my muscles were not in pain afterwards like they had been after previous long runs. I did not get the usual twitching and cramping. It was such a difference from what I was used to that I told my wife I almost felt like I was cheating! I used e-Gel during the Top Of Utah Marathon and took 17 minutes off my previous marathon PR. I easily qualified for Boston. This e-Gel is good stuff. I am glad I found it!
