Cruiser bike riders gear up for 203 Miles of Heartfelt Fundraising! 10,000 cyclists will ride 203 miles in the STP (Seattle to Portland Bicycle Classic). But in a few weeks, a team of 17 men and women will fly in from around the west coast and do something diehard bicyclists wouldn’t dare – ride a heavy, single speed 42-pound old fashioned beach cruiser in the Seattle to Portland Bicycle Classic.
