The ceremonial start of the 33rd annual Iditarod Trail Sled Dog Race across the US state of Alaska began in Anchorage on March 5, 2005, at 10 am AKST, and restarted in Willow the next day at 2 pm. After covering 1,161 miles (1,868 km) of wilderness, musher Robert Sørlie, an airport firefighter from Norway, crossed the finish line under the "burled arch" in Nome on March 16 at 8:39 am AKST. After taking care of his dogs, and an inspection to make sure all the mandatory equipment was in his sled, Sørlie was declared the winner by Race Marshal Mark Norman, with a time of 9 days, 18 hours, 39 minutes, and 31 seconds and won US$72,066.67 and a new truck. When asked how it felt to win a second time, Sørlie said "it feels good, I'm ready for breakfast." His team of dogs averaged 4.65 mi/h (7.58 km/h). The Red Lantern in last was Phil Morgan, an Alaska Airlines pilot, and when he crossed the finish line on March 21 at 8:02 pm AKST, the Widow's Lantern hanging on the burled arch was extinguished, which signaled the end of the race.

The Iditarod Trail Sled Dog Race, more commonly known as The Iditarod, is an annual long-distance sled dog race held in Alaska in early March. It travels from Anchorage to Nome. Mushers and a team of between 12 and 16 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.
