How Liu Xiang's Olympic tragedy turned triumph and became one of the most inspiring moments of the 2012 Olympic games.
This is China's Liu Xiang.
He won the gold medal at the 2004 Olympics in the 110m Hurdles, but has since struggled with problems with his Achilles tendon. It led him to drop out of the 2008 Olympics moments before he was set to compete.
But he worked to get back for London, and this morning he was ready to compete in the event he had once dominated the world in. It was clear before the race that this moment was special for him.
