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".
