Each year, during the Iditarod, packs of 12 sleigh dogs travel more than 1000 miles in 15 days. The animals working together pull the sled at speeds around 15 mph for up to six hours at a time. If running a marathon, Alaskan Huskies would cross the finish line in less than an hour and a half. Compared to the greyhound, which can sprint up to 45 miles per hour, the huskies are trained for distance and need to eat 10,000 calories per day during racing to generate the energy to run.
