     "London is ready to welcome the world," commission chairman Denis Oswald said. "We can feel that

London is feeling the fever of the games."

     On April18, the British capital marked the 100-day countdown to the opening ceremony of the

Games, which will be held from July 27 to August12, with a series of events. A giant set of Olympic

rings, made up of 20,000 flowers, were unveiled at Kew Gardens in west London. And the motto for

the London Olympics has been announced as "Inspire a generation."

     London 2012 chairman Seb Coe announced the motto. He said: "It is everything that we have been

saying since we started this extraordinary journey." Coe added that the motto is also a call for athletes to

come to the U.K. to perform at their very best and inspire the world.

     The preparations for the Games are proceeding according to plan-being both on time and within

budget, according to London 2012 chief executive Paul Deighton. Deighton said that millions of people

around the U.K. are getting ready to celebrate the biggest event in sport. "Eight million of the 11 million

tickets have been sold to people in Britain and we are sure that Brits will get hold of a chunk of the other

three million too."

     Many of the test events have already been held at the Olympic venues. And a bigger one will come on

the first weekend of May in the Olympic Park.

    Coe has been mentioned by the British media and British bookmakers as among the contenders to light

the flame, although his position as organizing committee leader always made that seem unlikely. Five-time

rowing gold medalist Steve Redgrave remains the betting favorite.
