Get ready to hit the trails on October 10th, 2026 (or October 11th if weather permits) for the 27th annual Soulstice Mountain Jackie Weintraub Memorial Trail Run near Parks, Arizona—and know that every dollar you spend goes directly to Big Brothers Big Sisters of Flagstaff! This volunteer-run event, organized by Northern Arizona Trail Runners Association, is currently sold out, but you can jump on the waiting list and even learn about becoming a mentor with Big Brothers Big Sisters. Plus, this year features Luke5Adventures of Flagstaff, a fantastic non-profit that brings hiking opportunities to people with mobility challenges throughout Northern Arizona!
