Organisers estimate that some 7.7 million tickets would be available for the Olympic Games, and 1.5 million tickets for the Paralympic Games. They will be going on sale in 2011, with at least 50% of these priced under £20. To reduce traffic, ticketholders would be entitled to free use of London’s public transportation network on the day of the event. It is estimated that 82% of available Olympic tickets and 63% of Paralympic tickets will be sold. There will also be free events: for example, the marathon, triathlon and road cycling.
