One person, on one yacht, traveling around the world. It's as simple as that. Founded in 1989, the Vendee Globe, considered one of the most grueling races in sailing, has been run every four years since '92. Ships depart out of France, down the African coast, round the Cape of Good Hope, around Antarctica, past Cape Horn, up the South American coast, and back to France. One person on one yacht. First one to make it back wins. The next race will be run in 2012.
