Discus is a field event in athletics where competitors throw a heavy disc-shaped object as far as possible. It is one of the four throwing events in modern track and field competitions, along with shot put, javelin, and hammer throw. DISCUS has been part of the ancient Olympic Games since 708 BC. The DISCUS is typically made of metal, wood, or plastic, and is thrown from a circle that is 2.5 meters in diameter.
