Thousands of runners donned iconic red and white-striped costumes in London for a "Where's Waldo?" themed fun run.

The event Sunday in south London saw thousands of men, women, and children dress as the titular character from the children's book series for a fun run that raised money for the National Literacy Trust.

Video from the event shows a sea of people dressed as Waldo -- known as "Where's Wally" in Britain -- jogging through Clapham Common.
