Route 66 Ultrarun

Route 66 UltraRun - November 14, 2026

The Route 66 UltraRun is the 5th annual ultramarathon held on Historic Route 66 in Arizona. The event is presented as a Certified Route 66 Centennial Event to mark the road's 100th anniversary. Organizers plan commemorative items such as artist-created belt buckles, enamel medals, and lapel pins for finishers.

The event offers two primary distances:

• 140 miles from Seligman to Topock66 with a 60 hour time limit
• 100 miles CenturyRun from Peach Springs to Topock66 with a 48 hour time limit

There are no intermediate cutoffs along either course. The routes pass through expansive valleys, piñon pine forests, rugged mountains, desert landscapes, marshes, and several stretches of Americana along Historic Route 66.

Entry types include Crewed Runners, Relay Teams, and Journey Runners. Crewed Runners must cover all miles on their own feet while using crew or pacers for support; crew limits are at least two and no more than four for the 140 mile race, and a maximum of two for the 100 mile CenturyRun. With prior approval, two Crewed Runners may share a crew if they remain together for the entire race.

Relay Teams compete within their distance division. Team sizes are three to six people for the 140 mile race and three to five people for the CenturyRun. There are no set leg lengths or fixed transition points; teams decide how to allocate running segments. Finishers who cross the line receive commemorative enamel medals and a finisher shirt featuring original Centennial artwork.
