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 award one 160 mile finisher a paid guaranteed entry to the Iditarod Trail Invitational.
Both distances require specific gear and are largely self supported. Checkpoints provide minimal support and organizers track competitors in and out of checkpoints only. Outside assistance from family, friends, or members of the public is not allowed. Participants are encouraged to use local businesses for purchases such as food or drink rather than relying on outside crew services.
Route details and checkpoint locations can change from year to year; organizers post route updates and course files when available. New event organizers have been announced and the next edition is scheduled for January 1 to 3, 2027 with registration opening in August.
