Definition:

Slalom ski races are traditionally the shortest race. They are comprised of close together turns or gates. Each competitor makes one run, then the course is reset on the same slope, but, with position of the gates changed.

Giant slalom (GS) races are similar to the slalom races, but, there are fewer gates and wider turns are needed to navigate through them in the GS.

As in slalom, skiers make two runs down two different courses on the same slope in the same day.

The times of both runs are added together, and the fastest total time determines the winner.
