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.

The race's namesake is the Iditarod Trail, which was designated as one of the first four US National Historic Trails in 1978. The trail in turn is named for the town of Iditarod, which was an Athabaskan village before becoming the center of the Inland Empire's Iditarod Mining District in 1910, and then becoming a ghost town at the end of the local gold rush. The name "Iditarod" may be derived from the Athabaskan "haiditarod", meaning "far distant place". Portions of the Iditarod Trail
