Seattle to Portland (STP)
Cascade Bicycle Club's iconic 206-mile road ride from Seattle to Portland — tackle it in one day or two through the Pacific Northwest's best scenery.
The vibe
Two states, one unforgettable weekend
The Seattle to Portland is the kind of ride that people put on bucket lists and then come back to do again every year. Cascade Bicycle Club’s flagship event covers 206 miles from Seattle to Portland, and you can either push through it in a single day (a feat that earns serious bragging rights) or spread it across two days with an overnight stop in Centralia. Either way, you’re looking at one of the most well-organized, well-supported long-distance road rides in the country.
The course rolls through the pastoral Puget Sound lowlands, past farmland and small towns, and eventually into the Columbia River corridor. Aid stations are stocked, SAG support is thorough, and the crowd is a genuine cross-section of Pacific Northwest cycling — first-timers riding their first century-plus alongside veterans chasing personal bests. The atmosphere on the road is social and encouraging rather than competitive.
Registration opens well in advance and sells out, so planning ahead is part of the deal. The finish line in Portland has that particular glow of shared accomplishment — thousands of riders arriving tired, sunburned, and grinning. It’s been running for decades and it still feels like an event.
