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. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity.The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
It is assumed that the ancestors of mankind developed the ability to run for long distances about 2.6 million years ago, probably in order to hunt animals.Competitive running grew out of religious festivals in various areas. Records of competitive racing date back to the Tailteann Games in Ireland in 1829 BCE, while the first recorded Olympic Games took place in 776 BCE. Running has been described as the world's most accessible sport.


It may seem obvious but In athletics running is involved in all track & field events. Teaching children good running technique/bio-mechanics at an early age will benefit them in all events.
