Molly Bookmyer, Elite marathoner, on making big fueling changes after Celiac's Disease Diagnosis

This conversation is published in full on the Lane 9 Podcast, episode 45.

"{Houston}was a really great season opener and showed me again that I could fuel, like I even fuel in the half marathon now. I'm able to take fuel and sustain my training and feel healthy and finishing strong in my races," shares Molly Bookmyer.

Bookmyer is an elite distance runner based in Columbus OH. She walked onto the Ohio State XC/Track and FIeld teams, but left the sport before graduating because of some frustrating injuries and health issues. She wasn’t getting regular periods, which actually led to her healthcare team discovering a small brain tumor.

After some time away from the sport she got back into distance running and eventually qualified for both the 2020 and 2024 Marathon Olympic Trials. While her marathon and half-marathon times have improved over the years—she ran a PR and won the 2024 Twin Cities Marathon in 2:28, and ran a half-marathon PR at the 2025 Houston Marathon with a 1:09—she has also navigated some intense challenges with gut health and fueling. 

We recorded this right before she traveled to DC where she ran the Cherry Blossom 10-miler, which she finished in 52:42, 8th overall female and 7th American. As she shared on Instagram, she “Ran over a minute PR in the 10 mile race and snagged a 10k PR of 32:11 in the process”. Next up for Bookmyer? The 2025 London Marathon, so we’ll be virtually cheering for her in a few weeks!
