About the race

Perpetua FatAss is on the Oregon Coast in Yachats, Oregon. The event offers multiple distances: 50K, 30K, 20K, and a 9-mile option, with route maps and GPX files available for planning. The atmosphere emphasizes community and simplicity—no entry fee, no medals, and a self-supported trail run along coastal terrain.

Participants refuel with water at two aid points and at the Cape Perpetua Center, and are encouraged to bring their own gear for a fully self-sufficient day. Afterward, runners join a casual potluck at the Yachats Commons, continuing the tradition of shared snacks and stories. This is the 12th annual edition.
