Kipchoge, 36, joins Ethiopia's Abebe Bikila (1960 and 1964) and East Germany's Waldemar Cierpinski (1976 and 1980) as the only runners to win back-to-back gold medals on the Olympic stage. The world record holder has now won four Olympic medals overall, having also taken 5,000m silver in 2008 and bronze in 2004. "I think I fulfilled the legacy by winning the marathon for the second time. Kipchoge finished in two hours, eight minutes and 38 seconds, coming in one minute and 20 seconds ahead of Nageeye. Kipchoge's triumph highlights Kenya's dominance in the Olympic marathon in recent years, with the men winning gold at three of the past four Games.
