If you haven't signed up yet for the Seattle to Portland (STP) Bicycle Classic, it's too late.
The Cascade Bicycle Club reported that the ride sold out as of Monday morning. That's the earliest that the 10,000 spots have sold out.
If you're still hankering to go, check the Cascade Event and Ride page in the future to see how they're re-distributing registrations for people who are seeking refunds. There's usually some kind of late registration within 29 days of the event. Monitor the Cascade blog or Twitter for more info.
There is no waiting list.
STP is a classic 200-mile ride from Seattle to Portland, scheduled this year on July 9-10. There are camping areas set up at several midpoints for people who want to complete the ride in two days; others knock out the ride in a single day.
Last year, registration filled up by April. Some details from last year's ride:
The oldest cyclist was 87 years old.
Eighty-two percent were veteran STP riders. Of them 230 had ridden in 10 or more STPs. Two of them, Jerry Baker and Paul Wantzelius, had done them all. [See Wantzelius obit.]
Cyclists participated from 43 states as well as Australia, Canada, Dominican Republic, England, Germany, Japan and Singapore.
