The Embark Oasis is the third and final checkpoint along the epic Arrowhead 135 route. Every year we gather a hearty group of volunteers, set up a couple of hot tents, light a bonfire, and have a 48 hour party in the woods of Northern Minnesota in January.

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 Tuscobia Winter Ultra is a human powered run, bike or ski event held on the Tuscobia and Wild Rivers State Trails in Northern Wisconsin, in the middle of winter.
