What event inspired the Iditarod?

The Iditarod was inspired by the 1925 serum run to Nome, also known as the "Great Race of Mercy." During this event, dog sled teams transported diphtheria antitoxin serum across treacherous conditions to combat an outbreak threatening the town of Nome, Alaska. The event highlighted the crucial role of sled dogs in Alaskan life and led to the establishment of the Iditarod Trail Sled Dog Race, first held in 1973, to honor this history and the endurance of the dogs and their mushers.
