About the race
The Route 66 UltraRun is scheduled for November 14, 2026 on Historic Route 66 in Arizona. The 5th Annual event is presented as a Certified Route 66 Centennial Event and commemorates the road's centennial and historical events tied to the corridor.
The event offers two main footrace options:
- 140-mile race from Seligman to Topock66.
- 100-mile CenturyRun from Peach Springs to Topock66.
The 140-mile race has a 60 hour time limit and the CenturyRun has a 48 hour time limit; there are no intermediate cutoffs. Both courses pass through expansive valleys, piñon pine forests, rugged mountains, desert landscapes, and marshes and include multiple iconic Route 66 stops.
There are several participation formats. Crewed Runners must complete all miles on their own feet with support from crew and pacers; crew requirements are at least two and no more than four for the 140-mile race, and a maximum of two for the CenturyRun. With prior approval two Crewed Runners may share a crew if they remain together for the entire race. Relay Teams may range from three to six members for the 140-mile race and three to five members for the CenturyRun; teams set their own legs and transition plans during the race.
Finishers who cross the line as Crewed Runners, Relay Team members, or Journey Runners receive a colored enamel finisher medal and a unique finisher shirt featuring original centennial artwork. Visit the organization's website for the most recent information.
