Huskies tearing through the streets of Anchorage mark the annual
start of the Iditarod Trail Sled Dog Race, a 1,049-mile trek
across the Alaskan wilderness that combines human and canine
athletic abilities. Although some native Alaskans in remote areas
still drive sled-dog teams for transportation, most sled dogs are
now used purely for sport. Mushers largely choose huskies to pull
their sleds as they are the best pullers, having been bred to do
so for thousands of years in the arctic.
