This is The Summit.
The Ultra is the final event in the Zero Dark Thirty Run Series — a progressive program designed to take participants from their first mile to 30 miles over the course of the season.
The Summit represents more than distance. It represents commitment, discipline, and follow-through. It’s the culmination of months of steady effort and the closing chapter of a journey that began with a single mile.
This event takes place near Veterans Day, honoring resilience, service, and the power of showing up — again and again.
This race is run/walk friendly, and participants may move at their own pace. Whether you run the entire distance or use a run/walk strategy, finishing is what matters.
All proceeds benefit the Zero Dark Thirty Foundation, a veteran-led nonprofit supporting veterans through movement, mentorship, and community.
