ARKTOS

ARKTOS is a winter ultramarathon held in Dousman, Wisconsin, within the Southern Kettle Moraine Forest, and part of the Golden Kettle Trail Series. It offers 6-, 12-, and 20-hour options for solo runners or relay teams up to four. Runners complete as many loops as possible on a snow-covered forest course within their chosen time frame.

The event is capped at 160 entrants and is described as an “uncommon group” with a rough-around-the-edges vibe and strong camaraderie. Special features include warming shelters, free bottomless coffee, tea or hot chocolate, a post-race chili (vegan option available), a wooden finishers medal, and ARKTOS glow wristbands.
