Iditarod: Toughest Race on Earth

The show follows and documents selected racers and their dogs during the 1,161 mile trek through Alaska's wilderness. Iditarod entrants pay $3,000 to enter the race and must have completed certain qualifying races beforehand. Expenses for the race can exceed $20,000 and mushers often seek sponsors to aide in paying for the race. Most mushers hold outside jobs in addition to racing.
