Iditarod Trail Sled Dog Race in neutral. An Alaskan husky in the Iditarod will burn about 9,666 calories each day; on a body-weight basis this rate of caloric burn is 3.5 times that of a human Tour de France cyclist. Similarly the VO2 max (aerobic capacity) of a typical Iditarod dog is about 240 milligrams of oxygen per kilogram of body weight, which is about three times that of a human Olympic marathon runner. Animal protection activists say that the Iditarod is not a commemoration of the 1925 serum delivery, and that race was originally called the Iditarod Trail Seppala Memorial Race in honor of
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
