Athletics (track-and-field) is not only the oldest but also the most popular sport. Running, jumping and throwing were popular in some ancient countries. Modern athletics began in the 19th century. Running races are held on open fields and later on at the stadiums, where athletes train and compete. The high jump, the long jump, the hop, step and jump are called field events. So are all the events in which the athlete throw something - a heavy weight, or discus, or a javelin. Running races call track events. The track is the ground that has been made for running on. The marathon race is run across country, so it's not a track event.
