The annual Soulstice Mountain Trail Run is a high-elevation race including a 30K, 11.2 miler, and 10K held at 7400 ft above sea level. The race is held in the middle of the Kaibab National Forest’s historic and Government Prairie. Throughout the race, you will have breathtaking views in all directions of Northern Arizona’s volcanoes, including the Arizona’s tallest mountain, the 12,633 foot tall San Francisco Peaks that tower over the course. The race is held on relatively flat, but rocky Forest Service dirt roads.
As our Forest Service permit limits us to a field of 200 runners, registration closes April 30th ahead of our May 1st lottery. If you don’t get in through the lottery (most do get in), your entry fee will be fully refunded right after May 1st.
RACE DETAILS:
Your registration fee includes a hi-tech colorful Sweatvac $30 value dye-sublimated t-shirt, race poster, Biff’s Bagels, live music, Fratellis 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, and calling it “one of the best post-race parties anywhere.”
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.
25 runners can guarantee entry by taking the Arizona Charitable Tax Credit to Big Brothers Big Sisters of Flagstaff ($470 per person, $938 per couple).
IN HONOR AND MEMORY OF:
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.
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.
MISSION:
Big Brothers Big Sisters of Flagstaff (BBBSF)
All of the proceeds from Soulstice, the post-race raffle, and Arizona Tax Credit donations benefit Big Brothers Big Sisters of Flagstaff (BBBSF). Race Director Neil Weintraub joined the Board of Directors shortly a month before running his first Soulstice race in 2001 and became a volunteer school-based mentor in 2002. After he retired from his job as an archaeologist for the Kaibab National Forest in 2020, Neil was matched in the community-based program with his little brother Zach, and they have had a blast together. One of their favorite activities is running the BBBRF 5K together, where Zach has PR’d the past three years!
Seeing the importance of mentorship to children in need, Neil has voluntarily directed both the Big Brothers Big Sisters of Flagstaff Half Marathon and Soulstice to raise funds in support of BBBSF programs. Revenues generated by these events help create and support one-to-one mentoring relationships that ignite the power and promise of youth.
THANK YOU!!!! Flagstaff runners strong!
THE VENUE:
With the race’s venue in Government Prairie, it is more family friendly than ever. This year we will be highlighting the historic Beale Wagon Road that is adjacent to the northeast side of the long course. NATRA’s friend Eric Souder and his camels Rakuda and Gamal will be at the Big Brothers Big Sisters of Flagstaff Aid station and we will have a photographer there to take pictures of you running by or with the camels!
