Haile Gebrselassie became the first runner ever to run a marathon in under 2 hours, 4 minutes. Last week, the Ethiopian clocked 2:03:59 to win his third straight Berlin Marathon, beating the mark of 2:04:26 he set last year over the same flat course. Gebrselassie dominated the world running scene in the 1990s, winning gold medals in the 5,000 meters and 10,000 meters and holding multiple world records. In the 2008 Beijing Olympics, however, the 35-year-old Gebrselassie did not medal, and some suspected that his running career was over. His world record marathon last week demonstrated that the world’s greatest distance runner is not done yet. Despite breaking the barrier of 2 hours and 4 minutes last week, Gebrselassie said that he doesn’t expect his record to last long.
