The transition from September into October brings a loaded race week across Oregon, with distances ranging from quick family-friendly fun runs to grueling ultras. It’s one of those perfect stretches of the calendar where the crisp mornings and fall colors line up beautifully with finish lines all over the state.
Whether you’re chasing miles on the trails, looking for a fast road race, or simply enjoying the seasonal festivities, there’s something happening almost every day.
And if you’re out and about that weekend, keep an eye out—you just might spot Run Oregon at the Perpetua Coast and the Portland Marathon.
