Can anyone give me more information about the difference between:

Oregon Bicycle Ride
http://www.oregonbicycleride.org/
(August 7-14 this year)

and

Cycle Oregon
http://www.cycleoregon.com/
(September 11-18 this year)

They seem like two very similar events, so aside from the routes and dates, can anyone tell me about the differences and similarities? My husband and I are confused about which one we should sign up for.

Thank you!
