2027 ST CROIX 40 WINTER ULTRA

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

All participants must be completed by 10:00 am Sunday morning. This means foot/ski racers have 16 hours to complete the course, and bikers have 12 hours. This requires a 2.5 mph average pace for people on foot/ski.

You also must be through the checkpoint (mile 20) by 3 am. This means that foot and ski have 9 hours (2.2 mph) and bikers have 5 hours (4 mph) to complete the first half of the course. Trust us, if you aren’t through the checkpoint by this time you’re probably not going to make the final cutoff.
