PORTLAND, OR -- For the first time ever, Cycle Oregon has canceled its annual ride. About 2,000 participants were scheduled to ride through areas like Tumalo, La Pine and Diamond Lake, starting next weekend. But, smoke from wildfires burning through the state forced event organizers to shut it down.

They say the route would be affected by smoke fiver out of seven days. They considered changing the route, but after discussions with the Oregon Department of Forestry, the US Forest Service, Bureau of Land Management and Oregon Department of Transportation, event managers decided it was safest to cancel.

Executive Director Steve Schultz posted a message on their website saying they're working on what to do next, and hope to have answers by next Wednesday. The ride was supposed to start September 9 and covers nearly 500 miles across Oregon.
