Show jumping, also known as "stadium jumping", "open jumping", or simply "jumping", is a part of a group of English riding equestrian events that also includes dressage, eventing, hunters, and equitation. Jumping classes are commonly seen at horse shows throughout the world, including the Olympics. Sometimes shows are limited exclusively to jumpers, sometimes jumper classes are offered in conjunction with other English-style events, and sometimes show jumping is but one division of very large, all-breed competitions that include a very wide variety of disciplines.
Jumper classes are held over a course of show jumping obstacles, including verticals, spreads, and double and triple combinations, usually with many turns and changes of direction. The intent is to jump cleanly over a set course within an allotted time. Time faults are assessed for exceeding the time allowance. Jumping faults are incurred for knockdowns and blatant disobedience, such as refusals (when the horse stops before a fence or "runs out"). Horses are allowed a limited number of refusals before being disqualified. A refusal may lead to a rider exceeding the time allowed on course. Placings are based on the lowest number of points or "faults" accumulated.
