A superb weekend of sport at the 2016 Olympics in Rio de Janeiro will come to a head on Sunday evening, as Jamaica's Usain Bolt will defend his 2012 gold medal in the 100-metre dash in the men's final.
Rio won't wait until then to entertain its crowds, though, and Kenyan Jemima Sumgong clinched gold in the women's marathon to kick off Sunday's schedule in style.
Silver and bronze were taken by Eunice Kirwa of Bahrain and Ethiopia's Mare Dibaba, respectively, but the athletics slate is only set to get shorter and sweeter as Sunday progresses, ending with the men's 100-metre crescendo.
