What are the skiing styles of cross-country skiing?

Cross-country skiing is divided into traditional skills and free skills, and the number of events set in this Winter Olympics is 50/50. The traditional technology limits the athlete's pedaling action, and the snowboard must be placed in a specially pressed snow slot, and the interval between two snow slots is 2-5 cm. There are two ways for athletes to move peacefully along the snow trough: one is to swing their legs back and forth, which is similar to walking with their legs on the normal ground; The second way is to use the snow pole to move forward, the athlete's feet are not moving, and the thrust is generated by the support of the snow pole, and every step forward will slide for a certain distance.

In the traditional technology, the pedaling action of athletes includes eight-step stepping, sliding and turning techniques when going up and down the slope, in addition to sliding alternately with both feet and pushing with two sticks. Downhill and smooth snowy road are the golden stages to surpass your opponent. When the rear athlete wants to overtake, he can step on the front athlete's snowboard to remind him. After being reminded, the front athlete must make way for the snowy road, otherwise it will be regarded as a foul.

Freestyle technique does not limit the pedaling action of athletes.

In the Beijing Winter Olympics, cross-country skiing is divided into two starting forms: intermittent starting and group starting. The combination of traditional technology, free technology, different distances and different numbers of people constitutes the cross-country skiing project group. Cross-country skiing routes include uphill, downhill and undulating roads, and each route accounts for 1/3 of the total length, so as to ensure that athletes can complete the climbing, turning, sliding and downhill techniques completely.
