Giant slalom (GS) is an alpine skiing and alpine snowboarding competitive discipline. It involves racing between sets of poles ("gates") spaced at a greater distance from each other than in slalom but less than in Super-G.

Downhill is a form of alpine skiing competition. Whereas the other alpine skiing events emphasize turning and technique, downhill emphasizes "the six components of technique, courage, speed, risk, physical condition and judgement", according to the FIS "International Ski Competition Rules (ICR)". Speeds of up to 130 km/h (81 mph) are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag and increase speed.
