Marathon world record-holder Eliud Kipchoge stormed to gold in one of the standout performances at the Tokyo Olympics on Sunday, with the curtain set to fall on the highly unusual Games.

A succession of big names have failed to perform at the postponed 2020 Olympics but Kenya's Kipchoge showed his class in Sapporo, kicking on the closing stages and clocking 2hr 08min 38sec to retain his 2016 title.
