Traversing over 8000 miles through Argentina, Chile, and Peru, the Dakar rally pits drivers and riders against each other and against extreme terrain. The 14-stage race attracts competitors from over 50 countries to race 465 vehicles - motorcycles, quad bikes, cars, and trucks - through deserts, rivers, and mountains. The race has seen its share of tragedy over the years, and the 2012 edition is no different, with Argentine motorcycle rider Jorge Boero dying after a crash near the end of the very first stage, and two spectators dying when their ultralight aircraft crashed. Begun on January 1st, the race concludes Saturday in Lima, Peru. -- Lane Turner (37 photos total)
