St. Croix 40 Winter Ultra
January 15, 2022 @ 6:00 pm - January 16, 2022 @ 10:00 am
The St. Croix 40 Winter Ultra is a 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.
