The Iron Dog race is the World’s longest, toughest, snowmobile race. It covers more than 2,500 miles through Alaska. This race takes place annually in mid-February. McGrath is a checkpoint for racers, and locals and non-locals see this as a big attraction. For those who are into snowmobiles/snowmachines, this is a great opportunity to admire the manufacturers newest models of machines and see how they compare across the rugged terrain of Alaska.
