The competitors can choose which of the 3 to 4 different lines they will ski down on the mogul course. The goal is to ski down the course as fast as possible, while performing two jumps without technical errors or temporary loss of balance.
The five ‘Turn' Judges award points on the quality of the skiers' turns and make deductions for technical mistakes, while the two "air" judges determine what jump was performed, how high they are off the jump, and the quality of the jump.
Each run is timed and compared to a pace time set for the course, with the fast skiers being awarded more points. The skier with the highest score in the final round wins.
Different mogul jumps include the 360 to 1080 degree spins, loops (side flips), off axis jumps, back and front flips and flips with twists. The jumps can have different grabs or holds of the legs or skis.
During the slopestyle competition, competitors are looking to get the highest possible score. To score points, riders must maneuver the course without falling and while performing the most difficult variety of tricks. Judges award points based on execution of the tricks, difficulty and amplitude.
Not restricted by formal structures and formats, ski cross is part of the FIS freestyle discipline. The majority of competitors have an alpine skiing background.
A timed qualification run is used to seed skiers into different heats, of four skiers each. At the sound of the starting device, the athlete begins racing down the course. The start, as well as the first sections before the first turn, are critical parts of the course, as passing can easily occur here. While other passing areas are designated on the course, interference with other skiers can lead to an athlete’s disqualification.
Each race is limited to four starters. The top half of the finishing field then moves on to the next round in a series of quarter, semi and final rounds.
During each heat, the first two competitors to cross the finish line advance to the next heat, while the last two competitors are ranked based on qualification times. The “big final” round determines which athletes place first to fourth, while the “small final” determines those who rank from fifth to eighth place.
There are five judges, each of whom examines the competitor on specific judging criteria: standard air, rotation, total judging of height and amplitude of manoeuvres, technical merit, incidental falls, overall impression. The 12 women and the 12 men who achieve the highest scores in the two qualifying runs progress to the final.
The final consists of two runs. The gold medal is awarded not to the person who has the best total score of the two runs, but the one who has the best individual run score.
