Plain Endurance Runs

Saturday, Sep 19, 2026 @ 5:00 AM

Location: 14400 Chiwawa Loop Rd, Leavenworth, WA

Events include Plain 100K and Plain 100 Miler.

The Plain races take place on USFS trails and roads in the Cascade mountains in the Lake Wenatchee, Entiat, and Chelan ranger districts. There are approximately 85 miles of trail and 20 miles of forest service roads, all quite remote. Elevation gain/loss is roughly 21,000 feet. This is a self-supported event. There is one re-supply point after the first 100K. Your water sources are creeks and rivers on the course and you will be carrying all your food and necessary gear from the start, or from the resupply point. Train for long, totally self-sufficient segments on a fairly difficult course with great scenery. This is a non-profit event. All proceeds go to local Search and Rescue and military veteran support groups.

For the Plain 100 Mile you must have completed a TRAIL 100 mile or the Plain 100K. A run/race equivalent to the Plain 100K, i.e. a very challenging event that requires a significant level of self-support and at least 15 +/- hrs on your feet, will be considered. There is no qualification required for The Plain 100K, but don't take this event/distance for granted. A challenging 50 miler would be a minimum level of ability.

Refunds: There are no refunds unless the event is cancelled. In this case, some funds will be withheld to cover direct expenses.

Registration closes: Mon, Aug 31 @ 11:59PM PT

Note: The event was cancelled for 2025 due to fire closures, but is planned for 2026.
