Soulstice Mountain Trail Run

Soulstice Mountain Trail Run is a volunteer-organized trail running event held at Government Prairie in Kaibab National Forest near Parks, Arizona on October 10, 2026, with a contingency date of October 11 if weather is severe. The event is the 27th running and is organized by the Northern Arizona Trail Runners Association; 100 percent of race proceeds benefit Big Brothers Big Sisters of Flagstaff. Dogs are not allowed on the race course.

Available distances include:

• 30K
• 18K (about 11.2 miles)
• 10K (about 6 miles)
• 1K Kids Dash

Early bird registration opens December 31, 2025 and remains available through January 7, 2026 at a reduced fee; after that a standard entry fee applies. The kids dash has a separate lower fee. Registration may be limited by a 200-runner Forest Service permit. If preregistration exceeds the permit limit by April 30, a lottery will be implemented; runners listed as legacy entrants registered before April 30 are guaranteed entry. Entrants may also guarantee their entry before April 15 by donating one Arizona Charitable Tax Credit to Big Brothers Big Sisters of Flagstaff. A May 25, 2026 update noted 35 spots remaining with specific counts for each distance. Visit the organization's website for the most recent information.
