Ride Idaho should be celebrating their 10th anniversary this year. Route and schedule will be announced on January 16, 2013.
Promises to be interesting.
Full dislcosure: This will be my ninth tour with this organization. I used to be involved with the planning and execution but now I just pay my money, get my recumbent and gear to the starting line and enjoy the ride. See my review of last year's event in this forum.
Limited to 300-350 riders, Ride Idaho is a week-long supported tour running 350-500 miles through Idaho's river vallerys, mountains, deserts, prairies, farms, ranches, and small towns. Amenities include professional mechanical and enthusiastic sag support, local food, a hot shower truck and entertainment at each camping site. If you have the money, a tent/porter service is available.
