Track and field is a sport that includes athletic contests established on the skills of running, jumping, and throwing. The name 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 racewalking. In the United States, the term track and field may refer to other athletics events, such as cross country, the marathon and road running, rather than strictly track-based events.
