Kaiser Permanente Seattle to Portland presented by Alaska Airlines

Saturday, July 13- Sunday, July 14, 2019



This 206 mile bicycle ride is the largest multi-day bicycle event in the Northwest with up to 8,000 participants riding from Seattle to Portland in one or two days. The route takes you through the scenic valleys, forests, and farmlands of western Washington and Oregon. Come ride what Bicycling Magazine has listed as one of the best cycling events in the nation!

The STP is a major economic boost to the area. Your registration fee not only supports Cascade Bicycle Club in its mission to improve lives through bicycling, but also contributes approximately $100,000 every year to schools, non-profits, and other community groups who provide services for our food stops and our finish fine.
