I DNFd my first race a few weeks ago: Miwok 100k, which I finished last year. No real reason to drop other than I wasn’t having a good time, and after 4-5 hours, I didn’t think it would turn around. No regrets dropping out, but I did sign up for Grizzly Peak Marathon with Coastal Trail Running a week later, and I came in 2nd. So that was a nice recovery / come back.
Zach won the half marathon too, so lots of hardware for our household!

Well done!
