About

The Route 66 UltraRun offers a 140-mile journey from Seligman to Topock66 and a 100-mile CenturyRun from Peach Springs to Topock66, both tracing the legendary Mother Road. Runners travel through sweeping valleys, pine forests, rugged mountains, deserts, and marshes while passing iconic Americana landmarks. The course nods to Route 66’s vibrant and storied past. With generous time limits—60 hours for 140 miles, 48 hours for 100 miles—and no intermediate cutoffs, runners of all abilities can soak in the scenery and history on this memorable ultra.
