Rules of cross-country skiing chase

Cross-country skiing competition involves two technical rules: traditional technique and free technique. Traditional techniques include alternating sliding, double stick sliding, eight-step non-sliding stage, sliding down and turning. Two feet or one foot of ice is not allowed. The skis must be placed in the pressed snow trough, and the two skis should be kept parallel to the sliding direction. Athletes can move forward by swinging their legs back and forth and having snowball fights. Athletes "step" forward is similar to walking, except that when skiing, they use snowball fights to generate thrust, and each step will slide for a certain distance. When they slide, they feel like sliding on the marble surface in smooth shoes. When overtaking the athlete in front, you can jump out of the snow slot and slide in the other direction, especially downhill and flat ski slopes are the golden stage of overtaking your opponent. When the athlete behind wants to overtake, he can step on the snowboard of the athlete in front to remind him. After being reminded, the athlete in front must make way for the snowy road, otherwise it will be regarded as a foul. Free technique has no restrictions on technical movements, and athletes can adopt any technical movements.

Cross-country skiing competition routes are divided into uphill, downhill and flat, each accounting for one-third of the whole journey. The highest point of the snow trail shall not exceed 1800 meters.

Snowboards should be marked. According to the regulations, the snowboards worn by athletes from the starting point to the finishing point must be printed with the marks marked by the referee at the time of departure, because the bottom of the snowboard is coated with snow wax, which is very smooth and helps to slide. Marking is to prevent athletes from changing skis halfway.

Interval departure:

In this event, the women's competition 10 km and the men's competition 15 km. An athlete starts every 30 seconds, and the ranking is determined by the time to reach the finish line. The athlete who spends the least time wins.

Set out in groups:

In 2002, the group departure event was included in the official competition of the Winter Olympics. All the athletes set off in line at the same time, and the number of people who passed was determined by drawing lots. Women run 30 kilometers and men run 50 kilometers. During the competition, athletes are allowed to pass through the sports ground every 10- 12 minutes. In the end, the first player to reach the finish line wins. There are often more than 10 athletes sprinting in the competition, and the final champion depends on the photos taken by high-speed cameras.

Chasing the game:

Chasing includes traditional skills and free skills. This event is very similar to a group departure. All athletes line up to start at the same time, and the number of people who pass is determined by drawing lots. In the middle of the competition, the athletes enter the playground and then quickly change their skills and ski poles. Women skated 7.5km traditional technique first, then 7.5km free technique, and men skated15km traditional technique+15km free technique. In the competition, athletes pass the playground every 6-8 minutes, and the first athlete to reach the finish line wins.
