I have to admit, I was a bit skeptical when I first heard about the e-Gel marathon PR guarantee, but I figured I had nothing to lose by trying it and everything to gain by using it. I used e-Gel and e-Fuel in my training, but I saved just enough e-Gel packets to use during my marathon. At age 44, I am proud to announce that I ran the fastest marathon of my life and qualified for the Boston Marathon again for only the second time in 15 years of serious marathon training. Now, I have to admit, I owe it all to e-Gel! Trust me, I’m taking e-Gel along with me to Boston.
