STP - Seattle To Portland

The Seattle to Portland Bicycle Classic presented by Alaska Airlines is the ride of a lifetime! Join STP and celebrate the Pacific Northwest bucket list challenge in its 46th year. Bicycling Magazine calls STP "one of the best cycling events in the nation" because this ride is a treat for young and old. Heading south from Seattle and ending in Portland, Oregon, STP is a thrilling back-to-back double-century ride through urban and rural settings. Challenge yourself to bike 206 miles through western Washington in one or two days.
