Discuses are one of the most remarkable pieces of equipment used in Track & Field. They have a unique design that is used for throwing trials, usually taking part in the Olympic Games. Discuses can be made out of a variety of materials, such as cement, plastic, metal, and composites. The surface of a discus is also designed to achieve maximal aerodynamic efficiency during flight. Discuses have been used since Ancient Greece, in an event called the discus throw. In this event, athletes would throw a discus in an attempt to throw it the furthest. Modern discuses are the same today, but today's discuses are much more efficient than the ancients'. Olympics discuses are specially designed to be very streamlined and travel further than others. Discuses have also become collector items for many athletes and fans of the sport. Not only are there personalized discuses for athletes, discuses have also become a sign of achievement in some sports, as winning a discus event is an incredibly difficult feat. Not only that, discuses from certain Olympics are now memorabilia and are highly sought after by many people. This makes discuses both a very important tool and a symbol in the world of Track & Field.
