Winter Racing the Arrowhead 135

A middle-age working mother who does ultra-distance winter racing by foot, bike and ski in the depth of winter in the coldest parts of North America. There's the Arrowhead 135 that she has completed nearly a dozen times, and the Iditarod Trail Invitational where she's pushing her bicycle for days through the snowy Alaskan trail used by the Iditarod dog sled race. Her grit is admirable, and her explanation of how these challenges benefit her everyday life is noteworthy. It might make you want to bundle up and try a winter adventure race!
