An Iditarod racer is called a musher. A musher is the proper name of a dog sled driver, no matter if the driver is a professional dog sled racer or an amateur. Dog sled was the fastest method of overland travel for the native tribes in the Arctic regions of Russia, Canada and America. Mushers control their dogs by means of vocal commands. One of the commands used to get the dogs running is the word, "mush," although that command has fallen out of favor in recent years.
