Completing one of the below accomplishments would typically qualify an entrant for this year’s Arrowhead Winter Ultra; however, entry is not guaranteed. The race directors reserve the right to change the rules in the interest of safety and sportsmanship or for any reason deemed appropriate by the race officials. The race directors reserve the right to select entrants based on other important considerations, as well as due to the requirements of insurers, sponsors, the Minnesota State DNR and other regulatory agencies.

Basically, we look for both endurance and cold weather experience. Below are general guidelines – race veterans and volunteers get preference for entry.

Qualifying activities for runners:

  • Completing a prior Arrowhead 135, Tuscobia 160 or similar race.
  • Finishing 100 mile foot race or completed multi-sport event, including a 100 mile run. A race in winter conditions improves your odds of being selected and surviving.

  • Finishing 24 hour bike race, with minimum of 100 miles completed for off-road, or 200 miles on road. A race in winter conditions improves your odds of being selected and surviving.
