The Iditarod dogsled race has started in Alaska.

About 70 teams will complete over the next ten days in a 1,600 kilometre race over some of the world's toughest terrain.

The Iditarod began 40 years ago as a way to revive a dying dogsled tradition in Alaska.

Al Jazeera's Daniel Lak reports from outside Anchorage.
