David Rudisha - World Record Holder & Olympic Champion, 800m

At the London 2012 Olympics David Rudisha's victory in the 800 metres was labelled the greatest race ever seen over the distance. The Kenyan broke his own world record and the pace was so fast that even the last athlete across the line would have won gold at the previous three Olympics. Now David Rudisha is aiming to lower his world record even further and possibly go below the one minute forty second barrier which has never been breached. Rob Bonnet talks to David Rudisha about his greatest moments on the track and how his talent was spotted and nurtured as a boy in Kenya.
