Event Description

Experience fat tire biking and snowshoe racing on the unique winter trails starting at Prairie Dells.  Bikers start first with a journey up the Prairie River gorge before hitting the hills and lakes of Underdown for rides of 10, 15 and 25 miles.  Six-mile snowshoers will get to the majestic Prairie Dells while three-milers will take in the overlooks of the new Heinemania Loop.  The wonder of this place in winter is something that has to be seen to be believed. Courses will be well-marked.

You choose your adventure - fat tire bike or snowshoe. If you sign up for both, you automatically receive 50% of the snowshoe event during registration!
