    The name of the race comes from the name of an Alaska gold rush town, Iditarod. It means “distant” or “distant place.” It comes from one of the languages of native Alaskans.

More than sixty sled teams begin the race in Anchorage. When the teams reach the outskirts(郊外) of town, they get a taste of Alaska’s wilderness. For about two weeks, they will fight the unbearable cold, wind, snow, and ice to complete the race. The temperature on the trail is often well below zero degrees. The Iditarod trail extends for about a thousand miles. It has many rendezvous points. At these meeting places, the race teams “check in” to let the officials know how they are doing. Some teams get into trouble along the way. Officials will stop them and give them the help they need. For example, officials might stop a team’s progress to give first aid, or to collect an injured or tired dog. These dogs are well cared for and will be reunited with their owners after the race.

The Iditarod trail is an important part of Alaska’s history. A part of the trail was used by some heroic dogs and humans in 1925. In Nome, Alaska, many people were catching the deadly disease Diphtheria. So the whole town was in quarantine, or isolation, in order to stop this disease. The only way to get medicine to Nome was by dogsled. About twenty "mushers, "or dogsled drivers, offered to help. They wanted to save the people of Nome from this terrible disease.

Today the Iditarod race shows honors to this special heroic journey and to all of the journeys on the famous trail. As the race organizers say, the Iditarod is “the last great race on Earth.”
