Biking the Oregon Coast

I'm off to bike the Oregon Coast for a week with Mountain Man. This is our rough itinerary:

Saturday: Drive to Portland and check out the sites. Stay in Portland for night.
Sunday: Drive to Cannon Beach. Start Biking
Monday - Friday: Keep peddling south. We plan to cover about 230 miles which is a leisurely 40 miles per day.
Saturday: Catch a ride from Coos Bay back to Cannon Beach in the am, possibly more biking in the afternoon.
Sunday: loooooong drive home.

Wish me luck! I'll be sure to let you know how it goes!
