Iditarod Trail Sled Dog Race I The most famous event in the history of Alaskan mushing is the 1925 serum run to Nome, also known as the "Great Race of Mercy." It occurred when a large diphtheria epidemic threatened Nome. Because Nome's supply of antitoxin had expired, Dr. Curtis Welch refused to use it and instead sent out telegrams seeking a fresh supply of antitoxin. The nearest antitoxin was found to be in Anchorage, nearly one thousand miles away. The only way to get the antitoxin to Nome was by sled dog as planes could not be used and ships would be too slow.
