The Mushers of the Iditarod race over 1000 miles from Anchorage to Nome, Alaska.
The sled dog race commemorates an historic event of 1925, when 20 dog teams rescued the town of Nome stricken by a diphtheria epidemic,
by relaying precious serum 674 miles in just 27 hours.
(Due to severe winter conditions, the serum could not be flown by airplane).
Today, the race lasts approximately 12 days.
