Freerunning is a form of urban acrobatics in which the participants, known as freerunners, use city and rural landscapes to perform insanely, difficult movements to get from Point A to Point B in an aesthetically pleasing manner. The guys over at the Tempest Freerunning Academy made this sick video to celebrate the Grand Opening of their new Los Angeles based training center. You might remember them from their appearance on Conan a while back. The video starts out with a hot chick then features a Super Mario Brothers inspired set. These guys know how to flip out.
