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). 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.
In cricket, a runner is a team member who runs between the wickets for an injured batsman.
When a runner is used, the batsman stands in position and plays shots as normal, but does not attempt to run between the wickets: the runner runs for him. The runner occupies the injured batsman's crease when he is on strike, but takes up a position away from the pitch at the umpire's discretion, typically on a pitch parallel to that being used for the game.
When the injured batsman moves off strike, he then takes up the position near the square leg umpire (not at the bowler's end), and the runner stands next to the bowler's wicket as in the normal course of play.
A runner is a person who runs.

Lum or LUM may refer to:
Lumë (also called Lum and Lumi) is a village in the former Shtiqën Municipality, Kukës County, Albania, beside the Kirit River. At the 2015 local government reform it became part of the municipality Kukës. It is about 21 kilometres (13 mi) northwest of Shkodër by road.
It is part of the Lumë region. According to Johann Georg von Hahn, both the village and the region take the name from the Lumë stream.
Lum Invader (ラム・インベーダー, Ramu Inbēdā) is a fictional character and the female protagonist from Rumiko Takahashi's manga and anime series Urusei Yatsura. She is often believed to be the protagonist of the series due to her iconic status. However, Takahashi has stated that Ataru Moroboshi is the main character. She is named Lamu in Animax's English-language dub of the series, and in the Italian and French anime dubs as well; however she is still called "Lum" (pronounced with a long "u" per Spanish linguistic customs) in the Spanish anime dub. Her name comes from popular 1980s swimsuit model Agnes Lum, as well as Rumiko Takahashi's nickname of "Rum" or "Lum" (from the interchangeable sound of the R's and L's in Japanese).
Lum is considered a magical girlfriend, though significantly different from others such as Belldandy of Oh! My Goddess and Ai of Video Girl Ai. While the latter two are openly considered "ideal" women by the protagonists of their respective series, Ataru often indicates publicly that Lum is the opposite of ideal.
