Route 66 UltraRun - November 14, 2026
The Route 66 UltraRun is the 5th annual ultrarunning event held along Historic Route 66 in Arizona and is designated as a Certified Route 66 Centennial Event. The 2026 program features two long-distance options that start and finish along sections of the historic highway and pass through valleys, pinon pine forests, rugged mountains, desert landscapes, marshes, and sites of Americana.
Distances:
- 140-mile Crewed Runner from Seligman to Topock66.
- 100-mile CenturyRun from Peach Springs to Topock66.
Time limits are generous: entrants have 60 hours for the 140-mile course and 48 hours for the CenturyRun, with no intermediate cutoffs noted. Crewed Runners must cover all miles on their own feet while using pacers and support crew; crew size limits apply (140-mile crews require at least two and allow up to four; CenturyRun crews are limited to two). With prior approval, two Crewed Runners may share a crew if they remain together for the entire race.
Relay teams are permitted: teams of three to six for the 140-mile race and three to five for the CenturyRun. Relay teams compete against other relay teams in their division; there are no fixed leg lengths or transition points and teams determine their own running order and timing during the event.
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. Registration closes on October 1, 2026. Visit the organization's website for the most recent information.
