What is the height difference between the starting point and the end point of the sled slide?

The track is designed in the shape of the Greek letter Omega. The width of the road is 1.30 ~ 1.50m, and the retaining walls on both sides of the slideway need to be iced. The race track length is 1000 ~ 1400 m for men and 800 ~ 1200 m for women. Curves with a radius of 8m are 1 1 ~ 18. The average slope of the slideway is the same for men and women, ranging from 4 to10. The height difference between the starting point and the ending point is 70 ~ 130m.

Sleigh, also known as bobsleigh, sport sleigh or short sleigh. One of the sleigh sports. A movement in which you lie on your back with your feet in front and control the sleigh to turn and slide at high speed by changing your body posture.

The sled is made of wood and has a pair of parallel metal skateboards at the bottom. Skateboards should not be equipped with rudders and brakes that can operate skateboards. The luge slide is made of concrete or wood, which is the same as the track of snowmobile and prone sled, but the starting point is farther than the other two events.

Sleigh:

The sleigh is 70~ 140 cm long, 34~38 cm wide and 8~20 cm high. The sled is made of wood, with a pair of parallel metal skateboards at the bottom, and the width is no more than 45 cm. There is no rudder at the front of the sled and no brakes at the back. The upper part of the skateboard is a bracket. The inclined part in front of the skateboard can turn flexibly and conveniently, but the device is not allowed to operate the rudder and brake of the skateboard.

The weight of single seat is 2 1-25 kg, and the weight of double seat is 25-30 kg. The competition is divided into three groups: men's single seat, men's double seat and women's single seat. During the competition, the athlete sits on the sled, pushes the sled backwards by hand with the help of the starting railing, and lies on his back when sliding. He pulls the sled belt with one hand and lies flat on his body, changing the posture of his shoulders and legs, turning the sled and making it slide down the ice track quickly.

Players can choose the most ideal route to go forward and minimize the game time. When reaching the finish line, the athletes must sit on the sleigh, otherwise the results will not count. In the competition, the average speed can reach 130 km (80 miles), and the fastest speed can reach 145 km (90 miles). Single-seat roller skating 4 times, and the competition period is two days; Double skating twice, the competition cycle is one day.

The time spent in the game adds up, and the one with less time wins. When the results are equal, the winner is the one with the best downhill performance. The order of departure is determined by drawing lots.
