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.

Alpine skiing, or downhill skiing, is the pastime of sliding down snow-covered slopes on skis with fixed-heel bindings, unlike other types of skiing, which use skis with free-heel bindings. Whether for recreation or for sport, it is typically practiced at ski resorts, which provide such services as ski lifts, artificial snow making, snow grooming, restaurants, and ski patrol.
