Why run the Plain 100?

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. It’s like climbing Mt. Everest without the aid of supplemental oxygen. Hence our motto, “The Plain Endurance Runs are just Plain tough”. If you’re looking for the ultimate challenge you’ve come to the right place.

For those of you that want the Plain experience but don’t want the full meal deal, we have an entrée for you; the Plain 100K, one loop instead of two.  

We look forward to seeing you at our events!
