Course
The vertical drop for a GS course must be 250–450 metres (820–1476 ft) for men, 250–400 m (820–1312 ft) for women. The number of gates in this event is 56–70 for men and 46–58 for women. The number of direction changes in a GS course equals 11–15% of the vertical drop of the course in metres, 13–15% for children. As an example, on a 300 m (984 ft) vertical course, there would be between 33 and 45 direction changes for an adult race.
