Spectators display a banner at a pedestrian bridge over the running course showing support for the victims of the Boston Marathon bombing during the 2013 London Marathon in central London on April 21, 2013. Tens of thousands of runners flowed through the British capital Sunday in the London Marathon, after a solemn 30-second silence at the start for the victims of the bomb attacks at the Boston Marathon barely a week ago.
