The St. Croix Winter Ultra is an overnight fat bike ultra race in the spirit of the Arrowhead 135 and Tuscobia 160 with a shorter distance for those wanting to learn the survivalist ethos before trying a longer fat bike winter ultra.
Riders start in their bivvy, ride through a cold Minnesota night, and have to perform a water boil in order to finish the race. Learn more about winter fat bike ultras at this event as you prepare for bigger challenges in the future.
The fat bike category now has 10 spots remaining. Learn more or register here.
