Ultra athletes compete in International Falls Ultra Marathon

The temperature was about 13 below in International Falls when over 100 athletes started the Arrowhead 135 Ultra marathon. More than 100 competitors will spend the next couple of days skiing, biking or trekking on foot in Northeastern Minneaota for a distance of 135 miles.
