17. Kenenisa Bekele- 2008 Summer Games
Ethiopian distance runner Kenenisa Bekele might be one of the greatest living distance runners in the world, if not the best. He is most known for his runs in the 2008 Summer Olympics but he also happens to have both a gold and silver medal from the 2004 Summer Games too.
However, it was at the 2008 Summer Games where he gave us some of the best performances at the Olympic Games we have ever seen. Bekele ran two events here, the 5,000m and 10,000m distance races. However, not only did Bekele win both events, he set the World and Olympic Record for his time in them that are still in place today. He ran 12:57.82 for the 5,000m & 27:01.17 for the 10,000m.
