*Slight NSFW, I believe I caught an F bomb or two near the end* Freerunning is insane, and this is freerunning at its insanest. This video is part of a an urban sports series called “Concrete Circus” featuring a trio of guys who take part in a team called “Storm Freerun”. I like how it wasn’t quite extreme enough so they decide to light the guys on fire. Wait for the bails and outtakes at the end.
