Soulstice Mountain Trail Run
The Soulstice Mountain Trail Run takes place on October 10, 2026 (October 11 if weather is severe) at Government Prairie in Kaibab National Forest near Parks, Arizona. The race is organized by volunteers from the Northern Arizona Trail Runners Association and other volunteer groups, with participants and volunteers also from the Luke5Adventures of Flagstaff Chapter. One hundred percent of race proceeds support Big Brothers Big Sisters of Flagstaff.
The event offers multiple trail distances:
- 30K
- 18K (11.2 miles)
- 10K (6 miles)
- 1K Kids Dash
Early bird registration opens December 31, 2025 and runs through January 7, 2026 at a reduced fee of $70; fees increase afterward to $80 for the 10K, 18K, and 30K. The kids dash has a separate lower fee. Entrants may transfer between distances at no charge. The event holds a Forest Service permit limited to 200 runners; if registrations exceed the permit by April 30, a lottery will be implemented. Legacy runners registered before April 30 are guaranteed entry. It is possible to guarantee entry before April 15 by donating Arizona Charitable Tax Credits to Big Brothers Big Sisters of Flagstaff. For safety reasons, dogs are not allowed on the race course.
As of June 17, 2026, only 22 spots remained open. Visit the organization's website for the most recent information.
