This shot was taken around the twelfth mile of the London Marathon, just before Tower Bridge. The bride wasn't far behind the elite group, which was pretty impressive.
It was a warm day, and runners were advised not to wear costumes, but spectators were still treated to the sight of male brides, bearded nuns, Yoda, Forrest Gump, Wonder Woman, a lobster, a bee, and a man carrying a washing machine.
