U.S. beach volleyball players Kerri Walsh (R), 33, and her partner Misty May, 34, train for the London 2012 Olympics in Manhattan Beach, California, April 9, 2012. Beach volleyball will be one of the main attractions in London, with the competition taking place at a temporary venue in Horse Guards Parade, a stone's throw from Downing Street and Buckingham Palace. No one will be more in the spotlight than Walsh and May-Treanor, who won gold medals in Athens and Beijing and are favourites for a third title in London. And, yes, the Americans will still be wearing the standard bikini uniforms — not the more modest attire approved recently by the International Volleyball Federation.LUCY NICHOLSON
