Running is a means of terrestrial locomotion allowing humans and other animals to move rapidly on foot. It is simply defined in athletics terms as a gait in which at regular points during the running cycle both feet are off the ground, in contrast to walking, where one foot is always in contact with the ground. Ancestors of mankind developed the ability to run for long distances about four and a half million years ago, probably in order to hunt animals. Competitive running grew out of religious festivals in various areas.
