Track and field is a sport that includes many different kinds of athletic contests that are based on running, jumping, and throwing. The name used in North America is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and race walking. Though the sense of "athletics" as a broader sport is not used in American English, outside of the United States the term athletics can either be used to mean just its track and field component or the entirety of the sport based on context.
