The London Olympics are less than 100 days away. Across the world, many competitors still have to qualify for the 16 days of competition. Others are entering the final weeks of training. 300,000 people are expected to travel to the British capital for the Summer Olympic Games. The opening ceremonies are on July 27th. Wednesday marked the 100-day point. Sebastian Coe, the British runner who won two Olympic gold medals, is chairman of the London 2012 Organizing Committee. "It signifies, first of all, still an extraordinary amount of work still to do, but I think 100 days is a, you know, it sort of means something to people. You know, when you're talking about seven years, six years, five years, four years, but actually when you're really talking about days, and we're talking, you know, we're talking, I don't know 12 Wednesdays or something, I mean it's, it really is, is very close." The Olympic Park is mostly complete. The Aquatic Center is ready for the likes of American swimmer Michael Phelps. He will attempt to build on his record 14 Olympic gold medals.
