Plan Route 66 UltraRun

Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.

Edition notes: The fifth edition. The 140-mile race starts at 7:00 AM (Arizona time) on Saturday, November 14, 2026, in Seligman, and the 100-mile CenturyRun at 10:00 AM in Peach Springs; both finish at Topock66. The limits are 60 hours for the 140 (Monday 7:00 PM) and 48 hours for the CenturyRun (Monday 10:00 AM). Every runner carries a SPOT tracker, followed live on Trackleaders. The 2026 race is a certified Route 66 Centennial event, and 140-mile runners who reach the 100-mile mark at Donkey Haven also get a 100-mile buckle.
