Ever wondered what it's like to ride a mountain bike full-speed along a cliff?
Peruvian downhill mountain biker Alejandro Paz is taking viewers on YouTube on a test drive. Paz, 28, strapped a camera to his helmet and captures the wild ride as he charges down along the edge of a cliff at lightning speed.
Shot from the biker's viewpoint, the effect is dizzying but undeniably exhilarating.
The promotional video was shot in San Pedro de Casta, a village outside Lima, Peru, that's 3,200 meters above sea level, according to Dailypicksandflicks.com. It was posted by Paz on YouTube a week ago. Since then it's gone viral, racking up close to a half million views on YouTube and climbing to the front page of the social news site Reddit.com this week.
