Route 66 Ultrarun

Route 66 UltraRun

The Route 66 UltraRun is the 5th annual ultra event held along Historic Route 66 in Arizona and designated as a Certified Route 66 Centennial Event. The 2026 program includes two point to point races and relay options.

• 140 mile race from Seligman to Topock66
• 100 mile CenturyRun from Peach Springs to Topock66

Both races pass through expansive valleys, piñon pine forests, rugged mountains, desert landscapes, marshes, and locations of Americana. The event references historical moments tied to the route, including the 1928 Bunion Derby, Dust Bowl Oakie migration, the era of family road trips, and later decline and grassroots resurgence that led to official recognition of Historic Route 66.

Time limits are 60 hours for the 140 mile race and 48 hours for the CenturyRun, with no intermediate cutoffs. Crewed runners must complete every mile on their own feet while supported by crew or pacers; the 140 mile race requires at least two and no more than four crew members, and the CenturyRun allows a maximum of two. 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 for the CenturyRun. There are no fixed leg lengths or transition points. Crewed runners, relay team finishers, and journey runners who finish receive colored enamel finishers medals and a commemorative finisher shirt featuring original art. Registration closes Oct 1 at 11:59 PM MT. Visit the organization's website for the most recent information.
