TMC A-Mountain Half Marathon + 4-Miler + Family Mile
This event day in Tucson on October 18, 2026, offers multiple timed and untimed running options that circle the summit of A-Mountain and use an out-and-back segment along the Santa Cruz Riverpath. The half-marathon is a 13.1 mile certified route that includes a four-hour time limit. Age-group awards and prize money are offered for top finishers, and gift certificates to The Running Shop are provided for some age-group winners.
All participants in the half and four-miler receive a souvenir medallion and a race shirt; half-marathon registrants receive a technical shirt. Shirts and medallions are guaranteed for the first 1,200 registrants in the half and four-miler. Remaining shirts and medals are available at The Running Shop (3055 North Campbell) on a first-come, first-served basis through November. Post-race food, drinks, and other activities are listed for race day, and a local merchant offers a discounted drink after the event.
This race is part of the SAR Running Shop Grand Prix and the third race of the 2026 Gabe Zimmerman Triple Crown, raising funds for BEYOND-Tucson. Event pricing and updated registration tiers are published for each distance; a sample updated schedule for the half shows tiered fees beginning at $60 and increasing at several date cutoffs.
