Athletics: China's Olympic champion hurdler Liu Xiang retires

BEIJING (REUTERS) - China's Olympic gold medal-winning hurdler Liu Xiang announced his retirement on Tuesday, ending a run in the sport marked by records and frustrated by successive late-career injuries.

Liu, 31, became an icon in China after he won the country's first Olympic men's track and field gold medal in the 110 metres hurdles in Athens in 2004.

He also won a world championship in 2007 and held the world record in 2006 with a time of 12.88 seconds.

"I'm retiring. I want to start a new journey," Liu said in a message posted to his microblog, blaming injury for his decision. "Though I still have hot blood pumping through my heart, my leg has time and again told me no."

One of China's most popular athletes, his gold medal at the 2004 Athens Olympics brought him fame and fortune, but also placed a huge burden of expectation on him.

Liu's ambitions were checked when, despite being favourite to win his pet event in front of home fans at the 2008 Beijing Olympics, he was forced to pull out with an Achilles injury in his first-round heat.

At the 2012 Olympics in London, Liu was disappointed again by injury, crashing out of competition after stumbling on the first hurdle and ending his hopes of regaining the Olympic title.

Liu's retirement makes him the latest world-class Chinese athlete to sign off from competition in recent years, after the country's first grand slam tennis champion Li Na retired in September 2014 and former NBA basketball centre Yao Ming walked away from the sport in 2011.
