The general rules for setting the slalom courses are: *a number of direction changes are 30 to 35% of vertical drop (+/- 3 direction changes). *the gradient of the slalom course should be from 33% to 45%.
Full Answer
Begin with measuring For slalom, a course setter's tape is helpful to measure distances. These clip onto the gate above, then simply slide down in the direction you plan to set the next gate and go to the distance you are targeting. Look back up and down the hill to check your offset.
Giant slalom consists mainly of open gates. Each gate consists of two poles connected by a 75x50 cm rectangular flag capable of tearing or breaking away. In a single gate GS, only the turning gate is set. An outside gate is required for the first and last turn and on any delay gates. except for the first and last turn.
Open gates make up the majority of the turns on a slalom course. Open gates are generally spaced between 6 and 12 meters apart, depending on the age, developmental phase and ability level of the skiers. Closed gates These are when the outside pole is set vertically below the turning pole.
*the gradient of the slalom course should be from 33% to 45%. Who sets the course? Coaches of different skiers set the individual courses. The list of coaches (and skiers they represent) picked for creating runs is available at the FIS documents library here.
How to Set Up a Slalom Water Ski Course [Step-by-Step Guide]1 – Take or estimate measurements.2 – Get permission.3 – Setting up the buoys around the course.4 – Anchoring the buoys.5 – Lining up the buoys.6 – Properly aligning and distancing the buoys.
Moreover, GS gates must be placed as follows: the distance between open gates is 22 ± 5 m with a maximum of three gates, including delayed gates, at a maximal distance of 35 m. At the delayed gates, a minimum distance of 15 m between the two consecutive gates is required.
Course. The vertical drop for a GS course must be 250–450 m (820–1,480 ft) for men, and 250–400 m (820–1,310 ft) for women. The number of gates in this event is 56–70 for men and 46–58 for women.
The average incline is 33% but reaches 65% in some points, helping the skiers reach speeds of around 80 km/h.
Missing a gate in alpine skiing If a skier misses a gate, he or she is disqualified from the competition, unless he or she hikes uphill and successfully passes through the missed gate. However, the time expense for doing this often makes it not worth the effort.
around 50 mphFor reference, athletes who compete in giant slalom typically reach speeds of around 50 mph, while slalom skiers clock in around 43 mph. While downhill may be one of the most basic courses in alpine skiing, it's also one of the most dangerous.
Like the slalom event, the giant slalom consists of two runs, after which a skier's times are combined.
Super-G means super giant slalom. It combines the speed of downhill but the technical turning necessary of the giant slalom. The course winds more than the downhill course, but the gates are spaced out more so that the skiers can pick up speed.
As in the giant slalom, each skier makes two runs down two different courses on the same slope. The competitors are required to pass between all the gates, alternate red/blue pairs of poles. Both runs take place on the same day. The times are added together, and the fastest total time determines the winner.
According to this report a skier can pull up to 139 G's.
Olympic skiers subject their bodies to as much as 3.5 g's--more than space shuttle astronauts endure during launch--and to velocities that would earn them speeding tickets in most states.

Each National Ski Association affiliated with FIS may enter one (1) competitor in FIS World Cup races taking into consideration the following conditions: Slalom / Giant Slalom Minimum requirements: Maximum 140 FIS points in one of the five events (SL, GS, SG, DH, AC) on the valid FIS points list.
Limitation for the 2nd run (Slalom / Giant Slalom / DH): only the first 30 competitors from the 1st run are qualified. This limitation is not valid for the Alpine Combined (see art. 9.5.1).
In case of a SL, GS, (AC if 1st run = SL) event, competitors 1 to 15 on the board are obligated to meet at a certain time for the public draw.
Accreditations must be handed out to the teams. The FIS season accreditations for the different groups as well as special FIS access cards (for example press corridor, media centre, restricted finish area) are valid and will be accepted by the Organisers.
Athletes, team members and servicemen are entitled to free of charge Wi-Fi access within the Team hospitality or the Team area in the Finish area and in the Team hotels or other area(s) designated by the Organiser wherever feasible. Any costs for this access are the responsibility of the Organiser. The Organiser should also provide free of charge high speed Wi-Fi access to the media in the Finish area.
In cases of unusual conditions, the Chief Race Director has the authority to establish a suitable starting point below the minimal vertical drop. This will take place as early as possible.
The Organiser of an approved competition program is forbidden to add any additional race without request and support by the National Ski Association to the FIS and without permission of FIS.
Length: A typical slalom course is 850 feet (259 meters) long, but individuals can settle for 600 feet (180 meters) in length that approaches the space of both ends, but the most ideal size would be 2,000 feet (600 meters) in length. Width: A regular water ski slalom course that can be used for practice is 75 feet (23 meters) wide, ...
Width: A regular water ski slalom course that can be used for practice is 75 feet (23 meters) wide, and additional space up to 100 feet (30 meters) wide is welcomed for extra precautionary measures, making the minimum width of the course 275 feet (85 meters). But remember that the course requires a lot more water areas, ...
When consistently practicing slalom water skiing, begin challenging yourself by asking the boat driver to increase their driving speed whilst you are skiing, small increases are recommended up to 2 mph. Over time, you may try and work up to a speed of 35 mph or more, which is the speed that pros use.
The average distance of the entrance gate of the course to the first set of boat guides is 88.5 feet (27 meters).
People can make use of an area that is 75 feet (23 meters) wide for practice. The addition of width space is always welcomed in the sport since it provides more safety measures, a measurement of up to 100 feet (30 meters) wide is acceptable.
An official and the most ideal measurement of the whole course should be 2,000 feet (600 meters in length. The minimum measurement for its length is 600 feet (180 meters).
Using the short arm part of the material against the buoys, when you see that the square is perpendicularly aligned to the laid out buoys on the course, it is time to anchor the skier buoy at 10.35 meters mark to the boat guide buoy at the end. Repeat the process for the remaining buoys.
The four main disciplines of the World Cup of Alpine Ski Racing are slalom, giant slalom (GS), super-G and downhill. Because GS is the core discipline of alpine skiing, it was the exclusive focus of this study. Each race has its own specific course and terrain characteristics regulated by the International Ski Federation (FIS).
Measurements were taken for six age levels, which included a total sample size of 57 male athletes; seven were from the elite level (all of the elite athletes were older than 21 y), 11 were from the U21 level, 13 were from U18, 6 were from U16, 13 were from U14, and 7 were from U12.
In total, 192 run sections from 88 runs were recorded and analyzed. Comparisons in course setting between JO and the older classes were only made in the medium sections, due to the different number of observations. No significant difference was found between the JO and the older group.
The main finding of the study was that average course settings in young classes (U12, U14, U16) did not differ in comparison with the older classes (U18, U21, elite). However, compared to the medium and steep sections, the turning angles and horizontal gate distances were shorter in the flat sections.
The current study showed no differences in course setting between young and older groups. However, differences were found in the mean speed and turn phase parameters, more precisely in the completion and gliding phases.

The studies involving human participants were reviewed and approved by swissethics. Written informed consent from the participants' legal guardian/next of kin was not required to participate in this study in accordance with the national legislation and the institutional requirements.
Giant slalom is characterized as the discipline that requires the most technical skill: skiers race down the mountain through a faster and more open course than in Slalom. Giant slalom is similar to the slalom, with fewer, but wider and smoother turns. Each skier makes two runs down two different courses on the same slope. Both runs take place on the same day, usually with the first run held in the morning and the second run in the afternoon. The times are added together, and the fastest total time determines the winner.
Slalom is a timed event requiring the execution of many short, quick turns through two different courses. The slalom features the shortest course and quickest turns. As in the giant slalom, each skier makes two runs down two different courses on the same slope. The competitors are required to pass between all the gates, alternate red/blue pairs of poles. Both runs take place on the same day. The times are added together, and the fastest total time determines the winner.
Super G (super giant slalom) is the newest of the Alpine disciplines, combining the elements of speed from the downhill, while integrating high speed technical turns from the giant slalom. The course is shorter than downhill but longer than a giant slalom course. Each skier makes one run down a single course and the fastest time determines the winner. This race discipline is rarely held in Pennsylvania.
The International Ski Federation (FIS) point scoring system for ski races was developed in order to recognize the better performance of finishing fourth in one race with a one second behind the winner, as opposed to finishing second in another race with a time two seconds behind the winner.
The downhill event features the longest course and the highest speeds in alpine skiing. Racers attempt to record the fastest time during a single run with a minimum number of control gates. This race discipline is never held in Pennsylvania.
