A running track is an OVAL-shaped track that is used for running events such as sprints, middle-distance races, and long-distance races. It is typically made of a synthetic material such as rubber or asphalt and is usually 400 meters in length. The inside lanes are typically reserved for faster runners, while the outside lanes are used by slower runners. The running track is an important part of any track and field event, and it is used to measure the performance of athletes in various running events.
