Plain Endurance Runs

Plain Endurance Runs are held near Leavenworth, WA on U.S. Forest Service trails and forest roads within the Lake Wenatchee, Entiat, and Chelan ranger districts. The course uses roughly 85 miles of trail and 20 miles of forest service roads through remote sections of the Cascade mountains, with approximately 21,000 feet of elevation gain and loss.

Distances:

  • 100 Miler
  • Plain 100K

The event is self supported. Runners carry their own food and required gear from the start or from the single re-supply point provided after the first 100K. Water on course comes from creeks and rivers. The terrain and remoteness mean long, self-sufficient segments are required.

Qualification standards differ by distance. The 100 Miler requires prior completion of a trail 100 mile event or the Plain 100K, or an equivalent event that demonstrates similar self-support demands and prolonged time on feet. The Plain 100K has no formal qualification requirement, though organizers note a challenging 50 mile run as a minimum level of ability.

The event is organized as a non-profit and proceeds support local Search and Rescue and military veteran support groups. Refunds are not offered except if the event is cancelled, in which case some funds will be withheld to cover direct expenses. Registration closes Fri, Sep 3.
