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).

October 10th Race Times:

7 AM: 10K/18K Non-Competitive Early Starters and all 30K runners (4 HR, 30 min cutoff)

7:30 AM: Klostermeyer Kids' Camel Dash at Li'l Pup Ranch

8:00 AM: Competitive 10K/18K

Your registration fee includes a hi-tech colorful Sweatvac $30 value dye-sublimated t-shirt, race poster, Biff's Bagels, live music, Fratelli pizza at the evening post-race party at the Pay-N-Take, and FREE downloadable high resolution photos from all of our photographers. For these reasons, in 2011, Runner's World Magazine listed Soulstice as one of the top 32 trail races in the United States, calling it "one of the best post-race parties anywhere." READ THE STORY HERE.

As a result of the continuing long-term effects of three fires over the past decade, we will again hold the race just west of Flagstaff in the stunningly beautiful Government Prairie grassland. READ THE STORY HERE. 

25 runners can guarantee entry by taking the Arizona Charitable Tax Credit to Big Brothers Big Sisters of Flagstaff ($495 per person, $987 per couple) by taking the Arizona Tax Credit for Big Brothers Big Sisters of Flagstaff. 

Legacy runners with at least seven Soulstice finishes must register before April 30th to guarantee entry.  Once you register, there are no refunds, however, we will allow up to 10 deferrals into the following year's race.  150 runners have done the race at least seven times! See the list here.

Jacqueline Weintraub

The Soulstice Mountain Trail Run is held in the memory of race director Neil Weintraub's mother Jacqueline. Known to Flagstaff runners as Jackie, Neil's mom was a lifelong supporter of his running endeavors beginning with his first 15K at only 12 years old. Mom was at the finish line of nearly all his races that included six New York City Marathons.  When Neil voluntarily started directing Flagstaff events, Jackie would drive 11 hours from San Francisco just to help time the race and party with Soulstice runners.  Vibrant and involved, in the months before she unexpectedly passed away, Jackie had completed a 400 mile bike tour of the Northwest and enjoyed a dream safari in South Africa. READ NEIL'S "ODE TO JACKIE" HIGH COUNTRY RUNNING COLUMN HERE. 

In 2015 Neil renamed Flagstaff's beloved trail run after Jackie. A moment of silence has been held in her honor each year at the beginning of the race. 

We know Jackie's there on the mountain with us cheering on every runner. 

With the race's venue in historic Government Prairie, we will again highlight the historic Beale Wagon Road, which passes through the 30K course. NATRA's friend Eric Souder and his camels, Rakuda and Gamal, will be riding throughout the race, and you can take selfies with the camels at the post-race party!  Click here to learn more about the role camels played in the construction of the Beale Wagon Road between 1857 and 1859.

The race takes place on October 10, 2026. As our Forest Service permit limits us to a field of 200 runners, we will hold a lottery on May 1st if we exceed the limit by then. Otherwise, registration closes once we have reached that total. If you register between 6 PM on December 31st and January 7th, you will save $10. 

The first post-race party begins after you cross the finish line!  Take the short walk back to the beautiful Langner Ranch and enjoy live music by Paul Webber, snacks, and beverages! 

Around 10 AM we begin announcing awards, which are followed by the always epic Aspen Sports Big Brothers Big Sisters of Flagstaff raffle with over $5000 in sports and camping gear. So plan to stick around and enjoy the Langner Ranch's scenic views, live music, and camaraderie. 

At 6 PM, finish off your day by heading down to the Pay N' Take for free Fratelli's Pizza. It is a great way to chill and reflect on the race.

If you plan on driving out to test the course, please do so slowly and no faster than 15 mph, especially within the residential neighborhood that you will pass through to access the route. The residents I've met are excited about having Soulstice take place in Government Prairie, and we want to keep them happy!
