During the 1925 serum run to Nome, also known as the "Great Race of Mercy", 20 mushers and about 150 sled dogs relayed diphtheria antitoxin 674 miles (1,085 km) by dog sled across the U.S. territory of Alaska in a record-breaking five and a half days, saving the small city of Nome and the surrounding communities from an incipient epidemic. Both the mushers and their dogs were portrayed as heroes in the newly popular medium of radio, and received headline coverage in newspapers across the United States.
On March 19, 1927, Balto received a hero's welcome as they arrived at their permanent home at the Cleveland Zoo. Because of age, Balto was euthanised on March 14, 1933 He was mounted and placed on display in the Cleveland Museum of Natural History.
But many mushers today consider Seppala and Togo to be the true heroes of the run as together they covered the longest and most hazardous leg. They made a round trip of 261 miles (420 km) from Nome to Shaktoolik and back to Golovin, and delivered the serum a total of 91 miles (146 km), having run over 261 miles (420 km) in total,almost double the distance of any other team.
