LEARN ABOUT BEING A BIG HERE!
Welcome to registration for the 27th running of the Soulstice Mountain Jackie Weintraub Memorial Trail Run on October 10th, 2026 (or October 11th if the weather is too severe on race day). The Soulstice Mountain Trail Run is organized by volunteers, including the unpaid race director, from Northern Arizona Trail Runners Association (NATRA LLC). As a result, 100% of the race proceeds benefit Big Brothers Big Sisters of Flagstaff youth mentoring programs. Founded at the Soulstice post-race party in 2001, NATRA’s mission is to promote trail running in Northern Arizona to folks of all abilities. We organize group runs of 5 to 8 miles, rotating a mix of over 75 different trails on Saturday mornings. You can join our free lifetime membership here, which includes our twice-monthly newsletter.
Soulstice early bird registration opens at 6 PM on New Year's Eve and remains available through January 7th at $70 for any race (you can switch races at any time by going to your RunSignUp profile and transfer to another distance at no charge). After that, the fee will be $80 for the 10K, 18K, or 30K distance.
If we exceed our 200-runner Forest Service permit limit by April 30th, we will implement a lottery. All legacy runners registered before April 30th are guaranteed entry. You can view the list of 150 legacy runners here. Otherwise, Soulstice registration will stay open on a first-come, first-served basis until we reach our limit.
You can also guarantee your entry before April 15th, and run the race for FREE by donating one of your Arizona Charitable Tax Credits to Big Brothers Big Sisters of Flagstaff (See details below).
For many reasons, safety of all runners first, dogs are not allowed on the race course.
