The difference between cross-country snow poles and ordinary plasma

Cross-country skiing is divided into traditional skills and free skills, and the number of events set in this Winter Olympics is 50/50. Traditional technology has restrictions on athletes' trampling movements. Snowboards must be placed in specially pressed snow slots, and the interval between two snow slots is 2 to 5 cm.

In the traditional technology, the pedaling action of athletes includes eight steps, sliding down and turning when going uphill and downhill, in addition to sliding alternately with their feet and pushing with two poles. Downhill and flat snowy road are the golden stages to surpass his opponent. When the athletes behind want to overtake, they can step on the snowboard of the athletes in front to remind them.

When reminded, the athletes in front must give way to the snowy road, otherwise it will be regarded as a foul freestyle technique, and there is no restriction on the athletes' pedaling action.

Traditional technology, free technology and the combination of different distances and different numbers constitute the cross-country skiing project group. Cross-country skiing routes include uphill, downhill and undulating roads, each of which accounts for 1 minute 3 of the total length to ensure athletes.
