Midwest States 100

Midwest States 100 is a small-field ultramarathon held on the Ice Age National Scenic Trail within Chequamegon-Nicolet National Forest near Westboro, Wisconsin. The event offers three distances:

• 100 Mile
• 100K
• 50k

All races start and finish at W7969 Park Rd, Westboro, WI 54490. The majority of the course follows the Ice Age Trail, a National Scenic Trail that passes lakes, rocky terrain, open prairies, and forested sections. Runners return to the start/finish area at the 100k mark and may choose to finish there or continue toward the 100 mile finish.

The event maintains a grassroots, small-field atmosphere and uses trail sections supported by the Ice Age Trail Alliance and volunteers. Camping add-on is available for $35 and includes one two-man tent space plus one car or one small camper van on a group campsite; no camping is available at the start/finish line. Early bird registration pricing until January 15 is listed as $295 for the 100 mile, $235 for the 100k, and $155 for the 50k. Opening-day registrants receive an extra race swag item.
