Just found this thread; I'm 58 and ran my 4th half marathon since 2020 this year. I'm not in good shape, 5' 10" ~250, but I sign up for 5k's, 10k's and half's to get prepared for Elk season, which is never enough. I want to be down to 230 by 9/1. I'm not a fast runner and average 11 minute miles and like using the Brooks Glycerin shoes for running. I tried a pair of UA Charged and Speedlands but like the Brooks better. Would like to try a pair of Hoka's someday.
I have been watching ultra running films, which have been motivating me to sign up for a full marathon. Of the half marathons that I've done, I didn't feel like i had anything left in the tank to go another 13.1 miles. I am wondering if that was training or fuel or both?!?
