Foot, Ski or Bike… find out if you have what it takes in this short course, survivalist, winter adventure.

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.

The St. Croix 40 will be a unique experience. Not only will you need to traverse the 40 mile course distance, but you will also need to prove that you can utilize your survival gear at two different points of the race. All participants will start the race tucked in to their bivy sacks and sleeping bags, proving that you actually know how to put them together. Then, at the only aid station, participants will need to boil water, demonstrating that you can use your stove. These skill tests will better help prepare you for bigger challenges in the future.

Think you have what it takes for races like Arrowhead, Tuscobia, or Iditarod? Come find out at the St. Croix 40 Winter Ultra!
