Plain Endurance Runs
The Plain Endurance Runs take place in Plain in Eastern Washington and offer long distance trail formats with limited event support. The event presents minimal on course assistance: pacers, course markings, and aid stations are not provided. Volunteers staff checkpoints but leave runners to rely on their own navigation and resupply.
The event currently has an overall finish rate of about 50 percent; in the first eight years there were only four finishers. The organizer presents a single loop option for the shorter distance.
Distances
- 100 mile
- 100K one loop
Critical update for the current season: the event was canceled after the Little Giant fire burned onto the course and the Forest Service issued a closure that includes trails and checkpoint access roads. The closure will remain in place until snow, so no modified version of the race could be held this year.
Registered runners will receive a rollover discount for the 2027 event. If 2026 operating costs for permits and insurance remain stable, organizers state there should be no additional fee to race in 2027. Organizers indicated they will provide registration and rollover instructions by late September. Visit the organization's website for the most recent information.
