The Silver Anniversary ride of Cycle Oregon is coming to the Klamath Valley for the first time in a quarter of a century.. Organizers of the 25th Cycle Oregon tour say they've set September ninth through the fifteenth as the dates for this year's ride, which will cover a route up to 490 miles long. That will include an overnight stop in Klamath Falls. The route is always a closely-guarded secret until its official announcement. When that happened, all 2,200 spots were filled within thirty-two minutes. Cycle Oregon hasn't wheeled through the Basin since its first run in 1996.
