Plain Endurance Runs

Leavenworth, United States • 13 Sep 2025

Plain Endurance Runs take place in Plain, a town in Eastern Washington. The event offers two options: the Plain 100 and the Plain 100K (one loop). The atmosphere is starkly self-reliant: no pacers, no course markings, and no routine aid stations; volunteers staff checkpoints, but runners are left to manage themselves.

Historically, finish rates are low; about half of entrants finish, reflecting the course’s demanding nature. The race is described as “Plain and simple”—you versus the course, akin to Everest without supplemental oxygen. For those seeking a lighter challenge, the Plain 100K provides a single-loop alternative. Visit the organization's website for the most recent information.
