Education
At the Gran Premio Città di Lugano Memorial Albisetti he finished in sixth place, and then he walked to a personal best of 1:20:42 in the 20 km race at the Grande Premio Internacional en Marcha Atletica in Rio Maior, Portugal – a time worth third place at the meeting.
Career
He holds the senior Asian record for the 20 km with his time of 1:17:36 hours and is also the Asian, Chinese and junior world record holder over 10 km. He was the bronze medallist over 20 km at the 2012 London Olympics. He competed in his first 50 kilometres race walk the year after at the 2009 Chinese National Games.
The sixteen-year-old Wang managed sixth place in 3:53:00. He took to the major international circuit the next year – the 2010 IAAF World Race Walking Challenge. He was seventh at the Coppa Città di Sesto San Giovanni in May, and managed 21st place over 20 km at the 2010 IAAF World Race Walking Cup (his first international championship).
Having gained enough points on the circuit, he was entered into 10 km 2010 IAAF Race Walking Challenge Final and the race proved to be one of the quickest of all-time, with four men walking 38 minutes and under. Wang Hao was the home favourite for the race in Beijing, but it was Wang Zhen who topped the podium. He finished the race in 37:44 minutes (the joint second fastest mark of all-time with Erik Tysse) which was a new Asian record, as well as being the world junior record for the distance.
He ended the year with a runner-up finish behind Valeriy Borchin at the 2011 IAAF World Race Walking Challenge Final. His first race of 2012 was in Taicang and he broke the Asian record with a time of 1:17:36 hours – almost a minute improvement on his best. He was chosen for the Chinese Olympic team and went on to secure the bronze medal in the 20 km walk.
Finishing behind Chen Ding, he shared the honour of winning China's first ever Olympic medals in the event. He broke the Asian 10,000 m track walk record at the Chinese University Games later that year, knocking over half a minute of the former record with a time of 38:30.38 minutes.
Membership
Wang was a member of the Chinese team at the 2008 Olympic Games in Beijing but did not compete.
