Yukon Quest
High Quality Content by WIKIPEDIA articles! The Yukon Quest 1,000-mile International Sled Dog Race, or simply Yukon Quest, is a sled dog race run every February between Fairbanks, Alaska, and Whitehorse, Yukon. Because of the harsh winter conditions, difficult trail, and the limited support that competitors are allowed, it is considered the "most difficult sled dog race in the world", or even the "toughest race in the world".
