What is the general drop of the alpine skiing competition venue in winter sports?

The height difference between the starting point and the finishing point of the downhill field is 8-1m for men and 5-7m for women. The design of the line length should ensure that the best performance of men is not less than 2 minutes and that of women is not less than 1 minute and 4 seconds in the Winter Olympics and World Championships. In order to ensure the safety of the competition, in addition to inserting enough red and green indicator flags on both sides of the line, flag gates must also be set up in important areas (such as dangerous areas, slope conversion and bumps, transitions and areas where athletes are prone to slip in the wrong direction). The width of the flag gate shall not be less than 8 meters. Athletes must use the front end and both feet of at least one snowboard to cross the flag gate line in order to pass the flag gate correctly. If the height difference between the starting point and the end point of the venue fails to meet the requirements of the rules, a two-wheeled downhill race can be organized (but the minimum height difference should not be less than 45 meters). The results of the two rounds of competition add up, and the one with less time ranks first.

The venue for the slalom should be built on a hillside with a slope of 2-27 degrees. The width of the site shall not be less than 4 meters. The height difference between the starting point and the finishing point is 14-22 meters for men and 12-18 meters for women. There are 55-75 flag gates for men and 45-6 for women. Each flag gate consists of two flags and two flagpoles. Red and blue flag gates should be inserted alternately. The standard of the flag is 24X22 cm. The minimum distance between two flag gates shall not be less than .75m.. The width of the flag gate is 4 ~ 6 meters. The flag gate shall include an open flag gate (the connecting lines of two flag gate poles are perpendicular to the line direction), a closed flag gate (the connecting lines of two flag gate poles are parallel to the line direction) and 1-4 flag gate groups consisting of 3-4 flag gates, such as snake gates, spiral gates, triangle gates and diamond gates. The results of the slalom race are summed up by the results of sliding once on two different routes, and the one with less time ranks first.

The giant slalom venue is usually sloping and wavy, with a width of at least 3 meters. The height difference between the starting point and the finishing point is 35-4 meters for men and 26-35 meters for women. The number of flag gates should be 12 ~ 15% of the height difference. The flag gate is 4 ~ 8 meters wide. The minimum distance between the flag poles of the nearest two consecutive doors shall not be less than 1 meters. Generally, two-wheel skating is required in the giant slalom competition. The second round of taxiing can be carried out at the same venue, but the flag gate must be reset. The results of two-wheel skating add up, and the one with less time ranks first.

The super giant slalom site requires undulating terrain. The width shall not be less than 3 meters. The height difference between the starting point and the finishing point is 5-65m for men and 35-5m for women. The width of the flag gate is at least 6 meters for the open flag gate and 8 ~ 12 meters for the closed flag gate. The number of flag gates shall not exceed 1% of the height difference, but at least 35 for men and 3 for women.
