The Arrowhead Winter Ultra is a non-profit human powered ultramarathon on bike, foot or skis, covering 135 miles across the Arrowhead Region of Northern Minnesota from International Falls near the Canadian border to Tower, MN. The course follows a scenic, hilly, State multi-purpose trail under extreme winter conditions the first Monday of February.
There will be one race check point serving hot soup and water at a cabin about the midway point by Elephant Lake near the town of Orr. Otherwise, racers are fully self-supported with a cutoff time of 60 hours.
Winter temperatures in this area of Minnesota have been known to reach a record -60F degrees.
The 2008 event is open for registration until the November 15, 2007 closing date. The Minnesota DNR has set the participant limit to 75 overall and changed permit and trail marking requirements which contribute in part to an an entry fee increase.
