context_page_description: 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. A ceremonial start occurs in the city of Anchorage and is followed by the official restart in Willow, a city 80 miles north of Anchorage. The restart was originally in Wasilla through 2007, but due to little snow, the restart has been at Willow since 2008. The trail runs from Willow up the Rainy Pass of the Alaska Range into the sparsely populated interior, and then along the shore of the Bering Sea, finally reaching Nome in western Alaska. The trail is through a harsh landscape of tundra and spruce forests, over hills and mountain passes, and across rivers.
context_section_description: There are currently 26 checkpoints on the northern route and 27 on the southern route where mushers must sign in. Some mushers prefer to camp on the trail and immediately press on, but others stay and rest. Mushers prepare "drop bags" of supplies which are flown ahead to each checkpoint by the Iditarod Air Force. The gear includes food for the musher and the dogs, extra booties for the dogs, headlamps for night travel, batteries (for the lamps, music, or radios), tools and sled parts for repairs, and even lightweight sleds for the final dash to Nome. There are three mandatory rests that each team must take during the Iditarod: one 24-hour layover, to be taken at any checkpoint; one eight-hour layover, taken at any checkpoint on the Yukon River; and an eight-hour stop at White Mountain.
  In 1985, the race was suspended for the first time for safety reasons when weather prevented the Iditarod Air Force from delivering supplies to Rohn and Nikolai, the first two checkpoints in the Alaska Interior. Fifty-eight mushers and 508 dogs congregated at the small lodge in Rainy Pass for three days, while emergency shipments of food were flown in from Anchorage. Weather also halted the race later at McGrath, and the two stops added almost a week to the winning time.
