Cardiff-born Williams has followed in the family footsteps by choosing a career in sport; his dad was a British Lions and Welsh rugby player, his sister was involved in GB junior athletics and his brother also represents Wales in athletics.

He agonisingly missed out on the 2008 Olympics due to stress fracture in his foot. He sustained the injury while taking part in the Welsh Championships just two months before. It was the first time he had competed since suffering a similar injury a year earlier.

Back in business in 2010 he took silver, behind fellow Welshman Dai Greene, at the European Championships in Barcelona. Then, a few months later, he was on the rostrum once again. This time, at the 2010 Commonwealth Games in Delhi when he took bronze.

Williams achieved qualification to the London 2012 Olympic Games the hard way after falling in the trials in Birmingham before following up six days later with victory at the European Championships in Helsinki to book his place. He delivered a gutsy race to reach the semi-finals.

Former pupil of Ysgol Gyfun Llanharri, he first got involved in athletics at the school and now trains in North London with Dan Pfaff.
