Context_1 : Marja-Liisa Kirvesniemi (nee Hamalainen; born 10 September 1955) is a Finnish former cross-country skier. She was the big figure at the 1984 Olympics in Sarajevo, winning all three individual cross-country skiing events (5, 10 and 20km), and a bronze medal for Finland in the relay. In the process, she became the most successful athlete at the 1984 Winter Olympics. At the 1988 Winter Olympics in Calgary, she won another relay bronze medal, and at the 1994 Winter Olympics in Lillehammer, she won two more bronze medals in the 5 and 30km. Context_2 : Freestyle skiing is one of the six skiing disciplines contested at the Winter Olympic Games, and one of the youngest. In 1924, the first Winter Olympics featured Nordic skiing disciplines (cross-country skiing, ski jumping, and Nordic combined), while alpine skiing was first contested in 1936. Only at the 1992 Winter Olympics, in Albertville, France, were freestyle skiing events first held as official medal events. Before that, freestyle skiing was contested at the 1988 Winter Olympics as a demonstration sport, consisting of events for both men and women in three variants: moguls, aerials and ski ballet. In Albertville, moguls was the first-ever official freestyle skiing medal event; aerials and ski ballet were also held but still as demonstration events. The growing popularity of aerials convinced the International Olympic Committee (IOC) to add this freestyle discipline to the 1994 Winter Olympics official program. Moguls and aerials have thus been contested at every Winter Games since. Ski cross inclusion in the Winter Olympics program was approved at an IOC Executive Board meeting in November 2006, and the first events were held at the 2010 Winter Olympics. Context_3 : For the Winter Olympics, there are 22 venues that have been or will be used for cross-country skiing. The first events took near the main stadium. In 1936, the first efforts to hold all of Nordic skiing (Nordic combined, ski jumping) in one location took place. This was repeated in 1952. For the 1956 games, the venue was among the first in the Winter Olympics to meet the television needs of RAI, Italy's national broadcaster. The 1956 venue was constructed in an oblong 250 by area in an east-west direction with the Grand Stands facing south. A temporary venue was created for the 1960 Games which also included biathlon for the first time. The first permanent Olympic venue in cross-country skiing took place in 1980. For all of Nordic skiing and biathlon, the first time they were in the same location was at the 2010 Games. Context_4 : The sport of cross-country skiing encompasses a variety of formats for cross-country skiing races over courses of varying lengths according to rules sanctioned by the International Ski Federation and by various national organizations, such as the U.S. Ski and Snowboard Association (USSA) and Cross Country Ski Canada. International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games. Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing. It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation. Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment.
