Slalom is a competitive sport that involves navigating a course marked by a series of gates, typically set up on snow or water. In skiing, athletes ski down a slope while weaving between poles, aiming for the fastest time. In canoeing or kayaking, competitors paddle through a series of obstacles in a river or artificial course. The sport requires a combination of speed, agility, and precision. Slalom events are often held in various formats, including individual time trials and head-to-head races. It is featured in the Winter Olympics for skiing and the Summer Olympics for canoeing and kayaking.
