Running
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 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.

Famous quotes containing the word running:
““Would you—be good enough—” Alice panted out, after running a little further, “to stop a minute—just to get—one’s breath again?”
“I’m good enough,” the King said, “only I’m not strong enough. You see, a minute goes by so fearfully quick. You might as well try to stop a Bandersnatch!””

“I think that carrying a baby inside of you is like running as fast as you can. It feels like finally letting go and filling yourself up to the widest limits.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
“Tattoo-shops, consulates, grim head-scarfed wives;
And out beyond its mortgaged half-built edges
Fast-shadowed wheat-fields, running high as hedges,
Isolate villages, where removed lives
Loneliness clarifies. Here silence stands
Like heat. Here leaves unnoticed thicken,
Hidden weeds flower....”
—Philip Larkin (1922–1986)
