St. Croix 40 Winter Ultra

The St. Croix 40 Winter Ultra is a challenging 40-mile winter endurance event held in Hinckley, Minnesota, within St. Croix State Park.

Participants can choose to compete on foot, skis, or fat bikes, navigating a rugged course through cold nighttime conditions. This survivalist race emphasizes self-sufficiency, requiring racers to carry essential survival gear and demonstrate proficiency with it at two skill-testing checkpoints along the route. Designed as a preparatory challenge for longer winter ultras like the Arrowhead 135 and Tuscobia 160, the event offers a unique and demanding experience for those seeking to test their winter adventure skills.
