London mayor Boris Johnson admitted today that there would be “imperfections and things going wrong” as the capital coped with the Olympics.
He said staging the Games was a "gynormous" task but the opening of the first Olympics-only road Games Lane and the first big arrival of competitors had gone well.
Mr Johnson said that the reported time of four hours for one competitors' bus reaching the Olympic Village in east London from Heathrow airport was "more like two-and-a-half hours".
He added that journey times from Heathrow could come down to around one hour and that, once in the Olympic Village, athletes reported being "bowled over" by facilities.
He was speaking as he and Transport Secretary Justine Greening visited the Transport Co-ordination Centre (TCC) in south London, which has been set up to cope with the massive numbers moving through the capital during the Games.
