Make your reservations early if you need a place to stay. There will not be a hotel block. We highly recommend getting a room for the overnight of the 600k even if you are planning on riding straight through. Having the option and a place to shower and change/keep clothing and devices charging makes everything easier.
Loop 400k to Oregon, New Glarus, Evansville, Milton, and Darien. The route has an option of taking the very pretty but hard pack Sugar River Trail. Reflective gear and lights are mandatory.
Make reservations at the Best Western early - our block expires 30 days before the ride.
