Road Biking Oregon: A Guide To The Greatest Bike Rides In The State

I've read this book cover to cover and taken several of the rides. It is helpful to read the beginning of the book which defines how the difficulty of each ride is determined. They are then grouped into 4 classifications based on difficulty. The maps are accurate, as are the elevation guides. It is worth reading the detailed descriptions before you set out on a ride. If you are not a fan of hills, stick to the rides classified as "Rambles", if you choose otherwise you will have hills - (this is Oregon after all).
