Race Information

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.
