Helsinki, Finland, July 1952: Czech runner Emil Zatopek had plenty to smile about as he posed for a picture during a training session at the Olympic Games. Zatopek had already won the 10,000 meter race, and before the Games were over he would also capture the gold in the 5,000 and the marathon. The marathon victory was especially impressive, as he was running the event for the first time but still set a world record.
