Plain Endurance Runs

Event details

The Plain Endurance Runs take place near Leavenworth, WA, at 14400 Chiwawa Loop Rd. The races run on USFS trails and forest roads in the Cascade Mountains within the Lake Wenatchee, Entiat, and Chelan ranger districts. The course uses about 85 miles of trail and 20 miles of forest service road and is described as remote. Total elevation gain and loss is roughly 21,000 feet.

• 100 miles (two loops)
• 100K (one loop)

Support, logistics and entry

The event is self-supported. There is one resupply point after the first 100K. Water on course comes from creeks and rivers, and participants carry their food and required gear from the start or from the resupply point. Qualification is required for the 100 mile: completion of a TRAIL 100 mile or the Plain 100K, or an equivalent event, is accepted. There is no formal qualification for the 100K, though a challenging 50-mile event is suggested as a minimum level of ability. The event is run as a non-profit and proceeds support local Search and Rescue and military veteran support groups. The 2025 edition was cancelled due to Pomas fire closure boundaries affecting most of the course; the organizers plan to hold the event again in 2026. Refunds are not issued unless the event is cancelled; some funds are withheld to cover direct expenses in that case. Visit the organization's website for the most recent information.
