This is a version of Jim Krep's Original Baraboo ride adapted to start in Whitewater. It's a hilly ride ascending the Baraboo Bluff and with a chunk of the driftless in the middle. It then flattens out to Columbus before returning to rolling back to the finish at Whitewater.
There are several places to stay in Whitewater with the most inexpensive being the TriCounty Motel and the Super 8 (more expensive). A room is highly recommended for a 400k before and after the ride.
