Sled dog racing - online puzzles

Sled dog racing (sometimes termed dog sled racing ) is a winter dog sport most popular in the Arctic regions of the United States, Canada, Russia, Greenland and some European countries. It involves the timed competition of teams of sled dogs that pull a sled with the dog driver or musher standing on the runners. The team completing the marked course in the least time is judged the winner.

A sled dog race was a demonstration sport at the 1932 Winter Olympics in Lake Placid, New York and again at the Olympics in Oslo, and once more in the 1994 Winter Olympics in Lillehammer, but it did not gain official event status. Sled dogs, known also as sleighman dogs, sledge dogs, or sleddogs, are a highly trained dog type that are used to pull a dog sled, a wheel -less vehicle on runners, over snow or ice, by means of harnesses and lines.

Races

Sled dog races include "sprint" races over relatively short distances of 4 to 100 miles, mid-distance races from 100 to 300 miles, or long-distance races of 300 to over 1,000 miles (Iditarod). Sprint races frequently are two or three- day events with heats run on successive days with the same dogs over the same course. Mid-distance races are continuous events of 100 to 300 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.

Races are categorized not only by distance, but by the maximum number of dogs allowed in each team. The most usual categories are four - dog, six- dog, eight- dog, ten- dog, and unlimited (also called open), although other team size categories can be found.
