During the Mexico City 1968 Olympic Games, David won Britain's only athletics gold medal when he powered to victory in the 400m hurdles, setting a new world record by 0.82secs and establishing himself a true hero. He vowed never to race the distance again, but returned four years later in Munich to defend his title. He could only manage bronze in the 400m hurdles, but followed this up with a silver medal in the 4x400m relay. David can be counted as an official 'Superstar' after winning the BBC TV show twice, but the glory hasn't gone to his head. Far from it, David has gone on to found 21st Century Legacy which is a charity to inspire young people to develop their potential to the full. This is delivered through a schools programme and delivered by a host of Olympians, including David himself who remains actively involved.
