The term 'Track Shapes' can refer to a variety of shapes that are used in the sport of track and field. One of the most common shapes used is the oval, which is a closed shape with two symmetrical curves that meet at both ends. Ovals are often used for running tracks, as they provide a smooth surface for athletes to run on. They are also used for other track and field events such as long jump, high jump, and shot put. Ovals are also used in other sports such as cycling and motor racing.
