Plain Endurance Runs

Plain Endurance Runs, held near Leavenworth, Washington, feature challenging ultra-distance races including a 100-mile and a 100K event. The courses traverse approximately 85 miles of US Forest Service trails and 20 miles of forest roads within the Cascade Mountains, covering the Lake Wenatchee, Entiat, and Chelan ranger districts. Runners face about 21,000 feet of elevation gain and loss on remote, scenic terrain.

The event is self-supported, with only one resupply point after the first 100K; participants must carry all food and gear and rely on natural water sources. Proceeds benefit local Search and Rescue and military veteran groups. Visit the organization's website for the most recent information.
