The Yukon Arctic Ultra: Ultra Marathon Adventure Racing Across Canadas Frozen North

The Yukon Arctic Ultra has a strong claim to being the world's coldest and toughest ultra. In 2007 the race was stopped when temperatures dropped to -72C, and the trail covers more than 430 miles over frozen lakes, rivers, hills and mountains. This book is the story of how exercise physiologist Mark Hines came to be one of the first people ever to complete this epic race.
