List of sled dog races

The list of sled dog races contains dozens of contests created by supporters of mushing, the sport of racing sled dogs. It is unknown when the first sled dog race was held. Humans have domesticated dogs for thousands of years, and sled dogs have been used for transportation in Arctic areas for almost as long. The first sled dog race to feature a codified set of rules was the All-Alaska Sweepstakes, which first took place in 1908. This was followed in 1917 by the American Dog Derby, which was the first sled dog race outside Alaska or the Yukon. In 1932, sled dog racing was a demonstration sport at the 1932 Winter Olympics in Lake Placid, New York, but was not included in future games.

The most famous sled dog race is the Iditarod Trail Sled Dog Race, an annual 1000-mile competition in Alaska. It commemorates the 1925 serum run to Nome but was not begun until 1973. The Iditarod helped restart worldwide interest in mushing, which had been thought of as anachronistic after the spread of snowmobiles. Since mushing's resurgence, the sport has proliferated and sled dog races are hosted in towns around the world, from Norway and Finland to Alaska and Michigan. Due to the cold temperatures needed for sled dog racing, most races are held in winter in cold climates, but occasional carting events, typically known as dryland races, have been held in warmer weather. These are not included in this list because they do not use sleds.

There are three typical types of sled dog races: sprint, mid-distance, and long-distance. These types can be broken down into sub-types. Sprint races cover relatively short distances of 4 to 25 miles/day, mid-distance races cover a total of 100 to 300 miles, and long-distance races cover 300 miles to more than 1,000 miles. Sprint races frequently are two- or three-day events with heats run on successive days with the same dogs on the same course. Mid-distance races are either heat races of 14 to 80 miles per day, or continuous races of 100 to 200 miles. (These categories are informal and may overlap to a certain extent.) Long-distance races may be continuous or stage races, in which participants run a different course each day, usually from a central staging location. Stage races are similar to cycling's Tour de France.
