Freerunning is an athletic and acrobatic discipline incorporating an aesthetic element, and can be considered either a sport or a performance art, or both. Freerunning is similar to parkour, from which it is derived, but emphasizes artistry over efficiency and speed. Freerunning involves interacting with physical obstacles in creative ways, such as by climbing, jumping or running; the obstacles may be purpose-built or may be part of a pre-existing natural or man-made environment. The movements are usually adopted from other sports, such as gymnastics, tricking or breakdancing. Freerunners can create their own moves, flows and lines in different landscapes. Practitioners of freerunning usually do parkour as well. Freerunning was founded by Sebastien Foucan, who discussed the subject in 2003 documentary film Jump London. Foucan developed freerunning as a more inclusive form of parkour. Parkour's efficient military style obstacle course training lends itself to martial art as a means of weapons avoidance and efficiently closing a distance to an opponent. Freerunning is derived from parkour, but it emphasizes not efficiency but artistry, allowing room for fancy flips and stylistic acrobatics. Etymology The word "freerunning" was first used in the documentary Jump London. The name was coined from a suggestion by Guillaume Pelletier, who was working with the group of practitioners at this time. In the documentary, freerunning was defined as an English translation of parkour. Philosophy The central principle of freerunning is that one should express oneself by moving fluidly in one's environment; there are no limitations on the form of this movement. Foucan expands on a number of basic principles of the sport in his book, Freerunning. Other practitioners have suggested other principles. For example, Daniel Ilabaca encourages people to think positively, suggesting that practitioners of freerunning will sometimes fall—largely because they think they might. History Origins in parkour In Western Europe, the idea of moving past obstacles for personal development or sport originated with Georges Hébert. He observed untrained native tribes in Africa with fantastic athletic ability and created the 'natural method' system to train people using the same ideas. His ideas eventually led to the parcours du combattant ('obstacle course', literally 'assault course'), which is now a standard of military training. These ideas were picked up by a young Raymond Belle, who used them to practical effect while separated from his family during the First Indochina War. When he moved to France and started a family, he passed
