STP Turns 40!  Let's celebrate!

Join us to help STP celebrate getting "over the hill", April 27th 4-7 p.m. at Cascade Bicycling Center.  Come celebrate the rich history of the Seattle to Portland and honor past riders, volunteers, and organizations that have kept this event going over the years.  It takes two states two put on this ride every year and CBC is grateful to all who have been involved.  

We'll have door prizes, trivia, food, beer (thanks Lagunitas brewing!) and live music!  Whether you are a future, current, or past rider there will be something for everyone.  RSVP to the party here.  



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.
