St. Croix 40 Winter Ultra

The St. Croix 40 Winter Ultra is an adventurous winter race held in St. Croix State Park, Minnesota, where participants can choose to compete on foot, skis, or fat bikes over a challenging 40-mile course.

This survivalist event not only tests endurance but also requires participants to demonstrate their survival skills at designated points along the route. Designed for those seeking to prepare for more demanding races like the Arrowhead 135 or Tuscobia 160, the St. Croix 40 offers a unique and rigorous experience in a cold winter setting.
