LONDON (AP).- More than a year before their athletes duel on the track, in the pool and on the playing fields, Olympic committees from around the world are engaged in a fierce competition in the host city of the 2012 Games. It has nothing to do with running, jumping or throwing. No medals are at stake. Yet plenty of prestige and money are on the line as national Olympic committees scramble to snap up some of London’s best-known landmarks for their hospitality houses and pavilions during the games. From Marble Arch to Alexandra Palace to Somerset House, Olympic bodies have picked historic venues to host fans, athletes, sponsors and VIPs and throw a party or two.
