Kenya's Eliud Kipchoge won the men's Olympic marathon with a dominating performance, running alone into the Sambadrome and finishing in two hours, eight minutes and 44 seconds on Sunday.
Ethiopia's Feyisa Lilesa claimed the silver medal and American Galen Rupp took the bronze on a soggy course.
Kipchoge, 31, has now won seven of the eight marathons he has entered, including two London Marathon victories.
In previous Olympic appearances, in 2004 and 2008, he had competed in the 5,000 meters before shifting his focus to the longer distance.
It marked the third straight time a Kenyan had claimed a spot on the Olympic podium, following silver and bronze performances in 2012 and a 2008 gold.
