Iron Dog: Seven Days to Survive Trailer [Video]

Few would question that one of the toughest tests of man and machine ever devised is the Tesoro Iron Dog, a 2,000-mile snowmobile (or snowmachine if you’re from the 49th state) race across Alaska.

While only a select few compete in this epic race every year, some adventurous filmmakers have tried to capture as much of the action and as possible in a new documentary called Iron Dog: Seven Days to Survive. We haven’t seen it yet, but there is a three-minute trailer available and we’ve included it at the bottom of this post. Enjoy.
