Iconic photo captures Usain Bolt's dominance

RIO DE JANEIRO, Brazil - Usain Bolt won a record third-straight Olympic gold medal in the 100 meters Sunday night, and may have posed for one of the greatest sports photos ever taken along the way.



Photographer Cameron Spencer captured this moment in Bolt's semi-final heat as the sprinter glanced back and smiled at the rest of the field as it struggled to keep up with him.

He went on to win the final in 9.81 seconds.

Bolt is attempting to win a 'triple-triple' - gold medals in the 100 meters, 200 meters and 4x100 meter relay at three straight Olympics.

Twitter had some fun with the picture:
