The Physics of Land Yacht Sailing - Surreal "Boats-on-wheels" in the Nevada Desert
(CNN) -- Over 300 miles from the nearest ocean, competitors in one of the world's fastest sailing races are battling against a moody wind. A small army of boats -- if you can call them that -- carve across the Nevada desert. A stream of sand billows behind, caking each competitor's face in fine, white grit. "It's like Mother Nature has her foot on the throttle," says Russ Foster, who has been racing these peculiar yachts-on-wheels since the 1970s.

"But that's part of the challenge."
