Guor Marial is man without a passport or country. This is the story of a South Sudanese refugee marathon runner who battled his way literally to London and won his right to compete at the 11th hour. Fleeing for his life from a Sudanese labour camp is what taught him to run. He escaped but not before his jaw was broken by soldiers. So when the IOC suggested he run for Sudan, Marial, who lost 28 members of his family in the civil war, refused. He chose to run as an independent runner under the Olympic flag in London. The 28-year-old reached the Olympic qualification time in October last year and improved his personal best in San Diego, California, last month, finishing in two hours 12 minutes 55 seconds.
