Cancellation Policy for 2021 edition: If the St Croix 40 Winter Ultra is cancelled due to issues surrounding the COVID-19 pandemic, or if international participants are banned from travel, participants will have two choices. 1) Participants can donate their entry to the race organization and forfeit their entry fee. This helps ensure a sustainable race organization going forward. 2) Participants can defer their entry until 2022 (with no additional charge), guaranteeing a spot in that year’s edition of the race. This deferral is for 1 year only and can not be postponed to future editions of the race. If a cancellation occurs, participants will be emailed directly to select their choice. As per our stated policy we will not be able to give refunds even in the event of a cancellation.

Foot, Ski, 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 in the race. These skill tests will help prepare you for bigger challenges in the future.

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