Plain Endurance Runs

Plain Endurance Runs : Leavenworth, WA

Plain Endurance Runs on September 19, 2026 take place on US Forest Service trails and roads in the Cascade Mountains within the Lake Wenatchee, Entiat, and Chelan ranger districts near Leavenworth, WA. The course covers approximately 85 miles of trail and 20 miles of forest service road in remote terrain, with total elevation gain and loss of roughly 21,000 feet.

The event is self supported. Participants carry their own food and required gear from the start or from the single re supply point available after the first 100K. Water is available from creeks and rivers along the route. The course requires long self sufficient segments and is described as fairly difficult with varied terrain.

Distances offered:

• 100K
• 100 Miler

Qualification standards differ by distance. Entry to the Plain 100 Miler requires prior completion of a TRAIL 100 mile event or the Plain 100K, or an equivalent very challenging run that involves significant self support and about 15 hours on foot. There is no formal qualification for the Plain 100K, though a challenging 50 mile event is suggested as a minimum level of ability.

The event is organized as a nonprofit. Proceeds support local Search and Rescue and military veteran support groups. Refunds are not issued unless the event is cancelled; in that case some funds may be withheld to cover direct expenses and organizers may consider special circumstances.
