Your STP registration makes Washington a better place for people riding bikes. The STP is a major economic boost to the areas we ride through. Your registration fee not only supports Cascade Bicycle Club in its mission to improve lives through bicycling, but also contributes tens of thousands every year to schools, non-profits, and other community groups who provide services for our food stops and our finish line.
