The Tuscobia Winter Ultra is a human powered run, bike or ski event held on the Tuscobia State Trail in Northern Wisconsin… in the middle of winter (read – on snow/ice/slush covered trails). Participants can compete in the 160-mile or 80-mile event.

All distances are semi-supported. This means that we will provide food/drinks and your drop bags will be available at the checkpoints. Patronizing local businesses is encouraged (be respectful of the space, don’t drag wet gear inside, don’t spread your stuff everywhere) and in that respect racers may use product/services of local businesses as long as no race rules are broken. But no other outside help, crews, or pacers is allowed. NONE. Racers may help racers. Even at checkpoints you may only receive aid from volunteers or other racers, and not from friends or family.

Run, Bike or Ski is defined as running, biking or skiing. If you aren’t sure your mode of transport fits the definition, it probably doesn’t. You are welcome to do the race via some other non-motorized mode (e.g., kicksled) and record a time, but will be considered in the “open” category, for which there are no prizes (sponsors welcome if they would like to step up) and “open” category participants will not be eligible for the ITI entry.
