Tuscobia Winter Ultra

The Tuscobia Winter Ultra is a challenging human-powered event held in Northern Wisconsin, featuring options for running, biking, or skiing. Participants can choose between an 80-mile one-way route or a 160-mile out-and-back course, with the latter serving as a qualifier for the Iditarod Trail Invitational. The event emphasizes self-sufficiency, requiring participants to carry essential gear and rely on minimal checkpoint support.

Local businesses are encouraged to be patronized during breaks. The event fosters a spirit of respect and common sense among competitors, making it a unique winter endurance challenge. Visit the organization's website for the most recent information.
