The Iditarod is an annual long-distance sled dog race held in Alaska, USA. The race covers a distance of over 1, 000 miles and is considered to be one of the most difficult sporting events in the world. The two main vehicles used in the race are dogsleds and sleds. Dogsleds are pulled by teams of huskies or other breeds of sled dogs, while sleds are pulled by a single person. Both vehicles are essential for completing the race.
