Route 66 UltraRun
The Route 66 UltraRun is the 5th annual ultramarathon organized as a Certified Route 66 Centennial Event. The 2026 program offers two long-distance options that run along historic sections of Route 66 in Arizona and pass through valleys, piñon pine forests, rugged mountains, desert landscapes, and marshes near iconic Americana sites. The race also acknowledges historical events connected to the road, including the 1928 Bunion Derby, Dust Bowl migrations, midcentury family road trips, the later decline after highway realignment, and efforts that led to recognition of Historic Route 66.
Distance options:
- 140 miles from Seligman to Topock66
- 100 miles from Peach Springs to Topock66 (CenturyRun)
Cutoff limits are 60 hours for the 140 mile race and 48 hours for the CenturyRun; there are no intermediate cutoffs. Crewed Runners must cover all miles under their own power with crew and pacer support; crew size rules differ by distance and require prior approval for crew sharing. Relay teams compete in a single Relay Team division per distance; team sizes vary and there are no fixed leg lengths or transition points, so teams decide and may adjust their running plan during the event.
Event registration closes October 1 at 11:59 PM MT. Finisher items for Crewed Runners, Relay Team members, and Journey Runners include commemorative enamel medals, original-art finisher shirts, and other centennial pieces such as artist-created belt buckles and lapel pins.
