Every year the STP sells out at our max. capacity of 10,000 riders.  If you missed this year's ride do not miss it next year!  Remember, members get the benefit of an entire month of registration for all of our events before they open to the general public.  If you are not a member do not wait to get your registration!  Get back on the site in December to get all of the details for registration dates.  

NEW this year: 

We're always working to offer riders the best riding experience possible. This year, we're excited to announce that a new route segment will take riders through Joint Base Lewis-McChord! Inside the military base, riders will not only enjoy comfortable, low-car roads, the military will display various military vehicles for a unique inside-look. 

Also with the renewed support of Group Health and the new addition of Alaska Airlines as our presenting sponsor, riders will receive a "Finisher" apparel item of their choosing (t-shirt, hat, etc) at the finish line in Portland as a souvenir this year.

And to top it all off, riders will receive a free meal at the finish line festival in Portland.
