Tuscobia Winter Ultra

The Tuscobia Winter Ultra is a human powered run, bike, or ski event held on the Tuscobia and Wild Rivers State Trails in Northern Wisconsin during winter. The event offers two distance options:

  • 80 mile one way
  • 160 mile out and back

The 160 mile distance requires completion of a qualifying event and serves as a qualifier for the Iditarod Trail Invitational. Organizers also provide one paid guaranteed ITI entry to a winner of the 160 mile race.

Both distances have required gear and are largely self supported with minimal checkpoint support. Outside assistance from family, friends, or strangers is not allowed. Participants are encouraged to patronize local businesses along the route; buying a soda or a meal is acceptable, while using facilities or services without paying is not considered appropriate support.

Checkpoints are used for in and out tracking only, and route marking can include flags, tape, and reflective materials. Course routing and checkpoint locations have changed in the past for safety or logistics, and participants should expect that routes may be adjusted. The event emphasizes responsibility, adherence to gear and rule requirements, and practical respect for the trail community and local resources.
