The two most recognizable stars heading into the 2012 London Olympics were American swimmer Michael Phelps and Jamaican sprinter Usain Bolt.
Over the week, British runner Mo Farah and American sprinter Allyson Felix have propelled themselves to the top of the Olympic who's who list, too.
Farah finished his golden double, winning the 10,000 meters on Saturday at Olympic Stadium a week after a spellbinding triumph in the 5,000.
