Tuscobia Winter Ultra

The Tuscobia Winter Ultra is a challenging endurance event held on the Tuscobia State Trail in Northern Wisconsin during winter. Participants can choose between two distances: 160 miles or 80 miles, with options for running, biking, or skiing. The 160-mile race serves as a qualifying event for the prestigious Iditarod Trail Invitational, and the winner receives a paid entry to the race.

Registration occurs annually in August, with specific qualifications required for the 160-mile distance. This event attracts outdoor enthusiasts looking to test their limits in a winter setting. Visit the organization's website for the most recent information.
