About Plain 100

Sat, Sep 13, 2025 • Plain, WA
The first eight years of the Plain 100 there were only four finishers! In time folks figured out how to manage themselves on our course. Approximately 50% now finish. In Ultra running circles, the Plain Endurance Runs are singularly unique. Plain isn’t just the name of a town in Eastern Washington, it describes this race itself. Plain and simple; it’s you and you alone against the course. You receive no aid in the form of; pacers, course markings or aid stations. Our volunteers staff checkpoints but, it’s Plain, they leave you to your own abilities. No pacers allowed on the course. No dogs allowed on the course (dogs are pacers).
