One of the great athletics rivalries of all time is renewed on Paris's roads as history-chasing Eliud Kipchoge faces three-time Olympic track champion Kenenisa Bekele in the marathon. The pair have been trading titles for more than two decades, but Kipchoge has changed the face of the marathon and is aiming to become the first person to win three successive Olympic titles over the 26.2-mile distance. The other medals decided early on today are in women's sport climbing and canoe sprint, while the final round of the women's golf also gets under way.
