Red Bull's Descenso del Cóndor urban downhill bike race is one of the most challenging of its kind. The high altitude course begins at 13,287 feet above sea level and includes more than 1,000 stair steps, nine drops and a handful of manmade jumps. Descenso del Cóndor, which was last run in 2006, took place again this October in La Paz, Bolivia. Watch the video for a taste.
