I found this listing for one of Grant's Getaways I thought was interesting. The web site is: http://oregonstateparks.wordpress.com/2 ... -bikeways/
This site has a lot of information about the Scenic Bikeways and it also a listing for the 2010 Cycle Oregon Week long ride. It shows elevation maps for several of the rides. The milage varies on several days so I don't know how accurate they are. To find the Cycle Oregon ride, go to the link to RIDE OREGON RIDE and click the right hand link to find Cycle Oregon Ride.
