Religious pilgrimages have existed much longer but they involve walking long distances for a spiritual purpose associated with specific religions.

Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions).
