I've mentioned here before that I'm a fan of Parkour (Google it - sometimes called "Free Running")
The guy credited with creating this urban combination of gymnastics and stunts is David Bell along with his friend Sebastien Foucan. I've seen heaps of videos but none compete with these two Parisiens. until now.
This "tracers.ru" clan are credited as Russian, (Actually Latvian; their russian nicknames are Ogre, John and Port), but these Free Runners are outstanding.
The video has a few crappy arty bits in the middle but some outstanding feats.
Enjoy Russian Parkour
