Paralympic swimming heroDavid Robertsmust look at his medal cabinet and wonder how to make space for his next haul.

He has notched up an incredible 16 medals (11 of which are gold) across the last three Paralympic Games.

At 24, he was awarded an MBE by the Queen. But it all started after David was diagnosed with cerebral palsy at the age of 11. He started swimming as part of his physiotherapy. Three years later, he was already swimming for Wales and, at 19, he travelled to the European Championships, winning all four of his events.

His Paralympic dreams came true in 2000 at Sydney with three golds, three silvers and a bronze. It was in Athens 2004 though, where his burgeoning potential was fully realised with four gold medal swims, one silver and two world records.  In Beijing in 2008, he secured a further four gold medals.

2006 saw Roberts represent Wales at the Melbourne Commonwealth Games and he excelled in 100m multi disability race, where - although he was only 0.02 away from his own World Record - he snatched bronze away from Australian Swimmer, Ben Austin.

In April 2011, David fractured his elbow, forcing him to withdraw from the International Disability Swimming Championships.

But this is the latest setback for Roberts, who in October 2009 suffered a fractured elbow, bruised ribs and a bruised right shoulder, while he has also had kidney stones and a broken foot in recent times.
