The event on October 18, 2026, in Tucson, Arizona, offers multiple race distances and community activities at the base of A-Mountain near the Mercado Annex and Mercado San Agustin. The half-marathon course circles the summit of Sentinel Peak (A-Mountain) and includes an out-and-back section along the Santa Cruz Riverpath. The four-mile route is an out-and-back that also circles the top of A-Mountain.

All half-marathon registrants receive a technical race shirt and a souvenir medallion. All four-miler registrants receive a colorful race shirt and a souvenir medallion. T-shirts and medallions are guaranteed for the first 1200 registrants in the half and four-miler. The half-marathon has a four hour time limit for runners and walkers.

The half-marathon is part of the SAR Running Shop Grand Prix and the event serves as the third leg of the Gabe Zimmerman Triple Crown, raising funds for BEYOND-Tucson.
