The Route 66 UltraRun returns to Historic Route 66 in Arizona on November 14th, celebrating the centennial of this iconic American highway with a series of challenging endurance races. The event takes place along various stretches of the historic route, starting from Seligman and finishing at Topock66 for both the full 140-mile race and the newly introduced 100-mile CenturyRun. On race morning, participants will gather in Historic Route 66 to begin their journey through Arizona's diverse landscapes. The trail conditions are expected to be firm but slightly soft underfoot, accommodating runners with a variety of terrain including expansive valleys, pinon pine forests, rugged mountains, desert landscapes, and marshes past iconic Americana landmarks along the way. Since its inception in 2016 as part of Route 66's centennial celebrations, the UltraRun has become an important event for endurance athletes who share a passion for history and adventure. The race commemorates significant moments in American history such as the Bunion Derby runners' footsteps from nearly a century ago and the Dust Bowl migration stories of the "Oakies". With each passing year, more participants join to experience this unique blend of athleticism and nostalgia. The Route 66 UltraRun offers multiple distances including both crewed and relay options. The course winds through scenic areas that are rich in history and natural beauty. Participants can expect a mix of flat stretches and challenging elevations as they traverse the diverse terrain along Historic Route 66 from Seligman to Topock66. Weather conditions on race day will feature firm trail surfaces with slightly soft spots due to recent precipitation, making for an authentic running experience that mirrors the real-world road conditions. UV index levels are expected to be low at 2.0, reducing concerns about sun exposure but still requiring proper hydration and protection against cooler temperatures typical of November in Arizona.
