Route 66 Ultrarun
Seligman, United States • 14 Nov 2026
Route 66 UltraRun
The Route 66 UltraRun takes place on November 14, 2026 along Historic Route 66 in Arizona. The event is the 5th Annual running and is a Certified Route 66 Centennial Event, marking the road's 100th anniversary.
The 2026 program includes two main race distances:
- 140-mile race from Seligman to Topock66
- 100-mile CenturyRun from Peach Springs to Topock66
Runners have generous overall time limits: 60 hours for the 140-mile race and 48 hours for the CenturyRun. There are no intermediate cutoffs. Courses pass through expansive valleys, pinon pine forests, rugged mountains, desert landscapes, marshes, and areas of Americana related to the Bunion Derby of 1928, Dust Bowl migrations, and the history of family road trips and later decline and resurgence of Route 66.
Entry types include Crewed Runners, Relay Teams, and Journey Runners. Crewed Runners must complete all miles on their own feet with crew or pacers; crew limits differ by distance (minimum two and maximum four for the 140-mile race; maximum two for the CenturyRun). Relay teams may have flexible sizes and choose their own leg lengths and transition points during the race.
Finishers who cross the line as Crewed Runners, Relay Team members, or Journey Runners receive a colored enamel finisher's medal and a unique finisher's shirt featuring original centennial artwork. Registration closes October 1, 2026. Visit the organization's website for the most recent information.
