Lopez Lomong: Sudan's lost boy

6 August 2012 Last updated at 12:35 ET Help

Olympic athletes have to go through many trials to get to the Games - but none more so than Lopez Lomong.

He was one of the so-called Lost Boys, thousands of child refugees caught up in Sudan's civil war, before he moved to the United States as part of a government resettlement programme.

On Wednesday, Lopez Lomong will represent the US in the 5,000 metre race at the 2012 Olympics.
