Half-Marathon Added to Colossal Vail 50/50

The Colossal Vail 50/50 presented by Fleet Feet Sports-Tucson isn’t just an ultra anymore! While running 55K or 50 Miles on the Arizona Trail remains at the heart of this event, we added a shorter distance for 2019 — the scenic and adventurous half-marathon features a segment of the Arizona Trail south of Colossal Cave Mountain Park as well as a sandy slog through a portion of Davidson Canyon. Runners will visit the aid station at Gabe Zimmerman Trailhead two times before their return to the finish line at Colossal Cave Mountain Park. The event is limited to only 100 runners. Register here.
