Soulstice Mountain Trail Run
The Soulstice Mountain Trail Run takes place on October 10, 2026 (scheduled; may move to October 11 if weather is severe) at Government Prairie in Kaibab National Forest near Parks, Arizona. The event is organized by volunteers from the Northern Arizona Trail Runners Association and other unpaid staff. One hundred percent of race proceeds benefit Big Brothers Big Sisters of Flagstaff.
Distances offered include:
- 30K
- 18K (about 11.2 miles)
- 10K (about 6 miles)
- 1K Kids Dash
Early-bird registration opens on December 31, 2025 and offers a $70 rate through early January; fees for the 10K, 18K, and 30K increase to $80 after that period. Entrants may transfer to another distance at no charge through their registration profile. The event operates under a Forest Service permit limited to 200 runners; if registrations exceed that limit by April 30 a lottery will be used, while legacy runners registered before April 30 are guaranteed entry. It is also possible to guarantee entry before April 15 by donating an Arizona Charitable Tax Credit to Big Brothers Big Sisters and receive free entry. As of April 6, 2026, there were 135 registered participants and 65 spots remaining. Visit the organization's website for the most recent information.
