Ok, the 'Official name' isnt 'freerunning' alright... Thats just what alot of people call it cause it is somthing people sitting at home watching tv can relate to. It's name is 'Le Parkour' as said by Sebastien Foucan and David Belle (the founders). Theres been other posts on farkin.net about Parkour too if you read back a year or so ^.^. Practitioners of this 'sport' (i dont like calling it a sport as it is non competitive) are called 'Traceurs'. I believe 'Le Parkour' means 'the way' or 'the route'. Visit
www.davidbelle.com (as name says) or
www.parkour.com (Sebastien foucans site) or
www.urbanfreeflow.com (largest UK and worldwide Parkour krew/group). The Urbanfreeflow people also known as 'Seidojin' have done ads for lots of European mobile phone and car companys. The latest video you can see some 'Parkour' in is on Madonna's - Hung Up (i think) video, Sebastien Foucan does a few moves. Visit
www.sydneyparkour.com for the sydney parkour webpage (barely ever updated) there are a number of people in Sydney, Melbourne, Perth, Brisbane and other cities in australia who practice Parkour. I myself am one of those people and we have regular practising sessions in sydney. PM me if you are interested although i am away until january.
Parkour is more than a sport, It's a way of living and a state of mind.
