Hats off to you, Marcelo Gutierrez, for laying down an absolutely mind blowing urban mountain bike run in Manizales, Colombia. <br /> <br />As if stray dogs, pedestrians, and crunchy terrain weren't enough, Gutierrez charges down the narrow streets of Manizales with ninja-like precision and steel cojones - making for one of the coolest (and sketchiest) POV mountain bike runs we've ever seen.
