The Iditarod race considered by some to be the hardest on earth is in its final stage in Alaska.

A total of 66 teams of dog-sledders - or mushers – are racing across the frozen landscape of the northern US state.

Dog sledding has been around for centuries and when it comes to the Iditarod, there is a lot of training and strategizing that goes into putting together the ultimate racing team.
