The Iditarod Trail Sled Dog Race is an annual long-distance sled dog race run in early March from Anchorage to Nome, entirely within the US state of Alaska. Mushers and a team of 14 dogs, of which at least 5 must be on the towline at the finish line, cover the distance in 8–15 days or more. The Iditarod began in 1973 as an event to test the best sled dog mushers and teams but evolved into today's highly competitive race. Teams generally race through blizzards causing whiteout conditions, sub-zero temperatures and gale-force winds which can cause the wind chill to reach −100 °F (−73 °C).

The Iditarod received more attention outside of the state after the 1985 victory of Libby Riddles, a long-shot who became the first woman to win the race. The next year, Susan Butcher became the second woman to win the race and went on to win three more years. Print and television journalists and crowds of spectators attend the ceremonial start at the intersection of Fourth Avenue and D Street in Anchorage and in smaller numbers at the checkpoints along the trail.
