Iditarod Trail Sled Dog Race early in the 20th century. The main route of the Iditarod trail extends from Seward in the south to Nome in the northwest, and was first surveyed by Walter Goodwin in 1908, and then cleared and marked by the Alaska Road Commission in 1911 and 1912. The entire network of branching paths covers a total of . Except for the start in Anchorage, the modern race follows parts of the historic trail. The trail is composed of two routes: a northern route, which is run on even-numbered years, and a southern route, which is run on odd-numbered years. Both follow
Iditarod Trail Sled Dog Race Avenue and D Street in Anchorage and in smaller numbers at the checkpoints along the trail. 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
