Slalom skateboarding is a form of downhill skateboard racing that first appeared in the 1960s and 1970s and has made a resurgence in popularity in the 2000s. Slalom racers skate down a course usually marked by plastic cones. The racer tries to get through the course with the fastest time, while knocking down the fewest cones. Each cone typically carries a penalty of a fraction of a second (most often 0.1 seconds) which is added to the skater's time.
