Plain Endurance Runs

Plain Endurance Runs, September 19, 2026

Plain Endurance Runs near Leavenworth, Washington includes two distances held on USFS trails and forest roads in the Cascade mountains. The event location is listed as 14400 Chiwawa Loop Rd, Leavenworth, WA.

The route traverses the Lake Wenatchee, Entiat, and Chelan ranger districts and uses approximately 85 miles of trail and 20 miles of forest service road. The course is remote and total elevation gain and loss is roughly 21,000 feet.

The event is self-supported. There is one resupply point after the first 100K. Water sources on course are creeks and rivers; participants must carry all food and necessary gear from the start or from the resupply point. The course contains long self-sufficient segments and requires training for sustained effort on a fairly difficult mountain route.

Qualification and policies are specified by the organizer. For the Plain 100 Mile a prior TRAIL 100 mile or completion of the Plain 100K is required, or an equivalent very challenging, self-supported run of roughly 15 hours on foot. No qualification is required for the Plain 100K, though a challenging 50 miler is noted as a minimum level of ability. The event is non-profit and proceeds support local Search and Rescue and military veteran groups. Registration closes Monday, August 31 at 11:59 PM PT. Refunds are not available unless the event is cancelled; some funds may be withheld to cover direct expenses. Visit the organization's website for the most recent information.
