[Historical Origin]
Cross-country skiing is a sport that glides in the mountains and snowfields with the help of skiing equipment, using basic techniques such as climbing, downhill, turning and sliding. Cross-country skiing originated in northern Europe, also known as Nordic skiing, and is one of the oldest sports in the world sports history. It was first included in the Winter Olympic Games in 1924.
The reason why cross-country skiing is called "snow marathon" is that the main competition is the endurance and physical strength of athletes. Cross-country skiing in the Winter Olympics has set a distance of 10 km, 15 km, 30 km, or even up to 50 km, which is equivalent to skiing a marathon. Because cross-country skiing is one of the events in nordic combined and Biathlon, it is also an important support for nordic combined and Biathlon.
As a routine of the Winter Olympics, the men’s 50 km and women’s 30 km cross-country skiing awards ceremony was held at the closing ceremony.
[Site facilities]
The cross-country skiing competition of Beijing 2022 Winter Olympics will be held at the National Cross-country Skiing Center in Zhangjiakou Division, and a total of 12 gold medals will be produced.
Cross-country skiing uses two techniques, and snowboarding is the most important: freestyle board is relatively short, the tip of the board is relatively small, the bottom is smooth, and all the wax needs to be slipped.
The traditional board has obvious bow-shaped arc, the sliding part needs sliding wax, and the middle pedaling part needs anti-slip wax.

[rules of the game]
Cross-country skiing competition involves two technical rules: traditional technology and free technology.
Traditional techniques include alternate sliding, double-stick sliding, eight-step without sliding stage, sliding down and turning. It is not allowed to push the ice with two feet or one foot. The snowboard must be placed in the pressed snow slot, and the two skis should be kept parallel to the sliding direction. The athletes can move forward by swinging their legs back and forth and using snowball fights. The athletes’ "stepping" forward is similar to walking, except that they use snowball fights to generate thrust when skiing, and they will slide for a certain distance every step. During sliding, they feel like sliding on a marble surface in smooth shoes. When overtaking the front athlete, you can jump out of the snow chute and slide in another direction, especially downhill and peaceful snow trail is the golden stage of overtaking your opponent. When the back athlete wants to overtake, he can step on the front athlete’s snowboard to remind him, and the front athlete must give way to the snow trail after being reminded, otherwise it will be considered a foul.
Free technique has no restrictions on technical movements, and athletes can adopt any technical movements.
