High Desert Ultra Running
The Colossal Vail 50/50 is an ultra running event held on portions of the Arizona Trail near the community of Vail, positioned approximately 24 miles southeast of Tucson. The event starts and finishes at Colossal Cave Mountain Park. The courses utilize sections of the Arizona National Scenic Trail located between Saguaro National Park and the foothills of the Santa Rita Mountains.
The terrain consists of high desert landscapes with rolling paths. The event was designed by the Tucson Trail Runners to provide a fast trail experience. This race serves as the first event in the Southern Arizona Triple 50 series.
Participants can choose from several distances:
- 50 Miles
- 55K
- Half-Marathon
The event follows a cupless policy to reduce environmental impact. Runners are required to bring their own hydration vessels or purchase reusable cups at the event, as open cups are not provided at aid stations. The race provides stocked aid stations along the route, emergency communications, and food for participants at the finish line.
Accommodations are available through local lodging options in the Vail area. The routes are set on expertly built trails that offer wide-open vistas of the surrounding desert environment. Visit the organization's website for the most recent information.
