Athletics is a group of sporting events that involves competitive running, jumping and throwing. The most common types of athletics competitions are track and field, road running, cross-country running, and race walking. 

The discus throw (pronunciation), also known as disc throw, is a track and field sport in which the participant athlete throws an oblate spheroid weight — called a discus — in an attempt to mark a farther distance than other competitors. It is an ancient sport, as demonstrated by the fifth-century-BC Myron statue Discobolus. Although not part of the current pentathlon, it was one of the events of the ancient Greek pentathlon, which can be dated back to at least 708 BC, and it is part of the modern decathlon.

Running is a method of terrestrial locomotion by which humans and other animals move rapidly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to sprinting.

Sport is a form of physical activity or game. Often competitive and organized, sports use, maintain, or improve physical ability and skills. They also provide enjoyment to participants and, in some cases, entertainment to spectators. Many sports exist, with different participant numbers, some are done by a single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs.
