[1] The width of the parallel skateboard shall not exceed 45cm. The front wing of the skateboard is allowed to keep a certain elasticity, but it is not allowed to operate the rudder and brakes of the skateboard. The weight of single seat is not more than 20kg, and that of two seats is not more than 22kg. Bobsleigh is made of metal, with a pair of movable steering plates at the front and a fixed streamlined cover attached to the steering wheel at the upper part. A brake is installed at the lower part of the tail. The double sleigh is 270 cm long and 67 cm wide, including the person's weight not exceeding 375 kg. The four-person sleigh is 380cm long, 67cm wide and weighs no more than 630kg. If the weight is insufficient, you can bring other heavier things to make up for it. During the competition, athletes are required to slide down and turn at high speed on the special ice and snow line by wooden or metal double-sled skateboard. The athlete sits on the sled, and pushes back with his hands by the starting railing to start the sled. During the sliding process, the athlete lies on his back on the sled, pulls the sled belt with one hand, and controls the sled to slide down the ice track quickly by changing his body posture. When reaching the finish line, the athlete must be on the sled, otherwise the result will be invalid. Because the lines are mostly S-shaped bends, the speed is extremely high, and the taxiing process is thrilling. There are snowmobiles similar to sledges. At present, only bobsleigh (also known as "sport bobsleigh" or "single bobsleigh") is used to compete with bobsleigh in the Winter Olympics. The sleigh is made of wood, and the bottom skateboard belongs to the whole genus. The width of a pair of parallel skateboards shall not exceed 45cm.

The starting order of the first round is decided by drawing lots. After that, we will rank according to the results of the last round, and the worst group will start first. After four rounds, the time to reach the finish line will be accumulated four times, and the final result will be obtained. The lower the number, the higher the ranking. If there is the same time, the team that finishes the game in the fastest time at any time will be the winner.
Edit the sleigh in this paragraph.
Bobsleigh, also known as "Long Sleigh", is a collective winter sport controlled by rudder and steering wheel. Its average speed can reach 90km to 100km, and the highest speed can reach 120km. Its sleigh is made of metal.
Edit the history of bobsleigh.
There are different opinions about the origin of bobsleigh. Talking about Britain which originated from1late 8th century. At that time, some British people installed a board on the bobsleigh. Later, a new sled was equipped with a metal rudder and brakes, making it possible to become the first sled in history.
Sled. Another saying is that it originated in Switzerland at the end of 19, but it was later proved that there was a record of wooden sleigh racing in New York State as early as 1880. Bobsleigh, like ski jumping, became an official event in the first Winter Olympics. At present, bobsleigh has set up three events in the Winter Olympics: men's doubles, men's four groups and women's doubles. There were only four men's events in the first two Winter Olympics, and the men's doubles event was added in the Jinghu Winter Olympics. Later, at the Winter Olympics in Salt Lake City, the women's doubles event became one of the events in bobsleigh, and Vanita flowers of the United States became the first African-American to win the Winter Olympics. Sleds are divided into bobsleigh and luge. Sleigh appeared in 18 in the 1980s. At that time, an American, a great warrior, nailed two single sledges together with boards, and the front one was used to control the turn. After the sled slid down the mountain road, it aroused great interest. This is the predecessor of bobsleigh. The sleigh appeared late. With the development of sledding, British skiers carried out solo sledding in 1948, and sledding was basically finalized in 1964. At the ninth Winter Olympics, this event was included in the official competition, and men and women played separately. Sledding has spread in Nordic countries since18th century. 1923, the world sleigh Federation was established, and there are dozens of member countries so far. Bobsleigh has been listed as an official event since the first Winter Olympics on 1924. From 1932, the third Winter Olympics, the men's double bobsleigh event was added. Because of the inconsistent venue conditions, this sport has no world record.

Edit this paragraph.
The luge, also known as "bobsleigh", "sports sleigh" and "short sleigh", is a winter sport for single and double people, and its sleigh is made of wood. At present, there are three events in the Winter Olympics, namely men's singles, men's doubles and women's singles. Athletes must be at least 15 years old.
Edit the history of this sled.
The history of luge is much earlier than that of bobsleigh. As early as the 8th century, there were sledge-like vehicles in Oslo. The first official international sled race in history was held in 1883 in Switzerland. At that time, European and Australian athletes skied for 4 kilometers, and finally an Australian team won. Later, in 19 13, the International Sled Federation was established. However, bobsleigh has become an official event of the Austrian Winter Olympics, including men's singles, doubles and women's singles. There is no gender difference in doubles events recently, but because only men have participated, it has become a men's doubles event over time. German, Italian and Soviet Union were the big winners in the bobsleigh event of the whole Winter Olympics, and they all won more than half of the medals in the bobsleigh event.
Edit this paragraph about bobsleigh and the Winter Olympics.
Bobsleigh has become an official event in the Austrian Winter Olympics. So far, there are three events: men's singles, men's doubles and women's singles. The sleigh used in the competition is made of wood. There is no rudder in front and no brakes in the back. There are only a pair of parallel metal sliding plates at the bottom, which are 34 to 38 wide, 8 to 20 high and 70 to 140 cm long. Because the sled has no steering wheel, it is more difficult to control than bobsleigh. At the beginning of the competition, the athletes sit on the sled and push the sled with their hands at the starting point. After reaching the finish line, the athletes have to stay on the sled, otherwise the results will not count. In men's and women's singles events, the weight of the sled used should not exceed 20 kg. Among them, the single race will be held for two days, and roller skating will be held twice a day. The first starting position will be decided by drawing lots, and the order of subsequent appearances will be decided by the results. The time gained by the four gliding events adds up, and the team with the shortest time wins. If the result is the same, the fastest team will win. In the doubles event, the maximum weight of sleigh is 22kg, and the activity lasts for one day, with two slides. The starting ranking of the first item will be decided by drawing lots, and the order of subsequent appearances will be decided by the results. Add up the time obtained in the two slides, and the team with the shortest time wins. If the result is the same, the fastest team will win.
Edit the part where the dog pulls the sled.
In foreign snow resorts, dog sledding is regarded as aristocratic entertainment. The sled pullers are generally purebred Siberian huskies, Alaskan sled dogs or Samoyeds. The rule of dog sledding: two people on one sledge. Usually, four or six strong sled dogs are placed in front of the sled, one sitting on a chair covered with deerskin, and the other standing on the skateboard of the sled behind. Tie the sled to the tree before playing. Once the rope is loosened, the dog will start to run forward. Dogs are not easily manipulated, so keep the sled stable, or put a hook in the snow to stop the sled. Once the hook is retracted, the dog will move on. Usually the sled dog in the front of the sled is commonly called "guide dog". The lead dog's job is not only to pull the sled as hard as possible, but also to motivate other sled dog members. The formation is 2-2-2-2; 1-2-2-2; 1-2- 1-2- 1-2; 1-7; 2-6 It's a different kind of enjoyment to play dog sledding in Hosa Regional Park in Finland. The terrain here is diverse, the weather is cold and full of thrills. Fabrice Lebel, director of the management department of 3 1 year-old, said, "The real situation is even more wonderful than I expected. Here you can not only enjoy skiing, but also experience driving. "
