Cross-country skiing
Cross-country skiing is a form of skiing whereby skiers traverse snow-covered terrain without use of ski lifts or other assistance. Cross-country skiing is widely practiced as a sport and recreational activity; however, some still use it as a means of travel. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport.
Modern cross-country skiing is similar to the original form of skiing, from which all skiing disciplines evolved, including alpine skiing, ski jumping and Telemark skiing. Skiers propel themselves either by striding forward (classic style) or side-to-side in a skating motion (skate skiing), aided by arms pushing on ski poles against the snow. It is practised in regions with snow-covered landscapes, including Europe, Canada, Russia, the United States, Australia and New Zealand.
Competitive cross-country skiing is one of the Nordic skiing sports. Cross-country skiing and rifle marksmanship are the two components of biathlon. Ski orienteering is a form of cross-country skiing, which includes map navigation along snow trails and tracks.
The word ski comes from the Old Norse word skíð which means stick of wood. Skiing started as a technique for traveling cross-country over snow on skis, starting almost five millennia ago with beginnings in Scandinavia. It may have been practised as early as 600 BCE in Daxing'anling, in what is now China. Early historical evidence includes Procopius's (around CE 550) description of Sami people as skrithiphinoi translated as "ski running samis". Birkely argues that the Sami people have practiced skiing for more than 6000 years, evidenced by the very old Sami word čuoigat for skiing. Egil Skallagrimsson's 950 CE saga describes King Haakon the Good's practice of sending his tax collectors out on skis. The Gulating law (1274) stated that "No moose shall be disturbed by skiers on private land." Cross-country skiing evolved from a utilitarian means of transportation to being a worldwide recreational activity and sport, which branched out into other forms of skiing starting in the mid-1800s.
Early skiers used one long pole or spear in addition to the skis. The first depiction of a skier with two ski poles dates to 1741. Traditional skis, used for snow travel in Norway and elsewhere into the 1800s, often comprised one short ski with a natural fur traction surface, the andor, and one long for gliding, the langski—one being up to 100 cm (39 in) longer than the other—allowing skiers to propel themselves with a scooter motion. This combination has a long history among the Sami people. Skis up to 280 cm have been produced in Finland, and the longest recorded ski in Norway is 373 cm.
Ski warfare, the use of ski-equipped troops in war, is first recorded by the Danish historian Saxo Grammaticus in the 13th century. These troops were reportedly able to cover distances comparable to that of light cavalry. The garrison in Trondheim used skis at least from 1675, and the Danish-Norwegian army included specialized skiing battalions from 1747—details of military ski exercises from 1767 are on record. Skis were used in military exercises in 1747. In 1799 French traveller Jacques de la Tocnaye recorded his visit to Norway in his travel diary: Norwegian immigrants used skis ("Norwegian snowshoes") in the US midwest from around 1836. Norwegian immigrant "Snowshoe Thompson" transported mail by skiing across the Sierra Nevada between California and Nevada from 1856. In 1888 Norwegian explorer Fridtjof Nansen and his team crossed the Greenland icecap on skis. Norwegian workers on the Buenos Aires - Valparaiso railway line introduced skiing in South America around 1890. In 1910 Roald Amundsen used skis on his South Pole Expedition. In 1902 the Norwegian consul in Kobe imported ski equipment and introduced skiing to the Japanese, motivated by the death of Japanese soldiers during a snow storm. Starting in 1919, Vladimir Lenin helped popularize the activity in the Soviet Union.
Norwegian skiing regiments organized military skiing contests in the 18th century, divided in four classes: shooting at a target while skiing at "top speed", downhill racing among trees, downhill racing on large slopes without falling, and "long racing" on "flat ground". An early record of a public ski competition occurred in Tromsø, 1843. In Norwegian, langrenn refers to "competitive skiing where the goal is to complete a specific distance in groomed tracks in the shortest possible time". In Norway, ski touring competitions (Norwegian: turrenn) are long-distance cross-country competitions open to the public, competition is usually within age intervals.
A new technique, skate skiing, was experimented with early in the 20th Century, but was not widely adopted until the 1980s. Johan Grøttumsbråten used the skating technique at the 1931 World Championship in Oberhof, one of the earliest recorded use of skating in competitive cross-country skiing. This technique was later used in ski orienteering in the 1960s on roads and other firm surfaces. It became widespread during the 1980s after the success of Bill Koch (United States) in 1982 Cross-country Skiing Championships drew more attention to the skating style. Norwegian skier Ove Aunli started using the technique in 1984, when he found it to be much faster than classic style. Finnish skier, Pauli Siitonen, developed a one-sided variant of the style in the 1970s, leaving one ski in the track while skating to the side with the other one during endurance events; this became known as the "marathon skate".
