After five failed attempts, I finished a 100-miler in March. If I’m being blunt, it’s because I finally did the things in ultramarathon training that you’re supposed to do. For years, I thought I could do one on my own, without help from a crew or pacers. I would go out too fast and hope I could hang on for the last 50K. (Spoiler alert, I could not). I didn’t eat enough, mostly because I approached the aid stations haphazardly, like a toddler trying to pick a snack before bed.
