About

Devil's Den Ultra is a trail event held in Bradford, Vermont, on October 10, 2026. It offers a 30-Hour and a 12 Hour timed race, both starting at 7:00 a.m., alongside a 6 Miler (9.7 km) that starts at 8:00 a.m.

Timed formats let you decide your own distance, which is what makes them approachable. The 12 Hour is an inviting first ultra: you can run and walk as you like and stop whenever you choose, with the total miles as your result. The 30-Hour is a different beast, stretching through an entire night and into a second day, and it suits runners who already know how they handle sleep deprivation and long hours on their feet. The 6 Miler gives friends and family a way to share the day on the same Vermont trails. For the timed races, build 16 to 20 weeks of training around long runs and long hikes, then add a night session to test your headlamp and cold-weather layers, since Vermont nights in October get cold fast. Fueling every hour and rotating dry socks will keep you moving.
