Dog race moved due to lack of snow

The competitors in the Iditarod Sled Dog Race in Alaska, US, had to travel more than 200 miles north to a more snowy start line.

The 33rd annual Iditarod got underway in Alaska yesterday, with 1,000 dogs and 78 sled drivers.

A warm winter meant there wasn't enough snow to hold the race on the traditional course.

Iditarod lasts for about 10 days and spans over 1,000 miles of snowy terrain.

The organisers also spread 350 truckloads of snow over the amended course to help it run safely.
