London Mayor Boris Johnson (2nd L), former Romanian gymnast Nadia Comaneci (3rd L) , London 2012 chairman Lord Coe (4th L), US track and field Olympic gold medallist Carl Lewis (C) and British swimmer Rebecca Adlington (4th R) pose during a photocall with 26 school children representing 26 different sports on the day the 2012 London Olympics tickets go on sale, in Potters Fields Park, London, on March 15, 2011. Tickets for the 2012 London Olympics went on sale Tuesday with organisers promising the website would not crash under the expected huge demand. Organisers are urging applicants to approach the start of the ballot for 6.6 million tickets as a marathon not a sprint with applications possible for six weeks.
