The St. Croix 40 Winter Ultra is an overnight winter survivalist race in the same spirit as the Arrowhead 135 and Tuscobia 160. Participants travel roughly 40 miles through St. Croix State Park on foot, ski, or fat bike, carrying all essential survival gear through a cold Minnesota night.

The event starts at 4:30 pm on Saturday January 14th, with the first race beginning at 6:00 pm.
