Ahead of the event, 12 competition winners were invited to scale the London landmark to take part in an Up at the O2 'reaping'. After a dizzying 52-metre climb up the side of the O2, one name was pulled from a special reaping bowl, and the winner - Ryan Crane - bagged the once-in-a-lifetime prize of a trip to the world premiere of Catching Fire in 2013.
