Rio Olympics 2016: Usain Bolt wins 200m gold, his 8th Olympic gold medal

Usain Bolt won the mens 200m to claim his second Rio 2016 gold, his eighth at an Olympics, and keep alive his hopes of an unprecedented treble treble. The Jamaican ran 19.78 seconds to come home ahead of Canadas Andre de Grasse and Frances Christophe Lemaitre. Britains Adam Gemili clocked the same time as Lemaitre, but was denied his first Olympic medal in a photo finish. Bolt, 29, has already won the 100m in Rio and will run in the 4x100m relay final on Friday Bolt is aiming to match his achievement of claiming gold in the 100m, 200m and 4x100m relay at both Beijing 2008 and London 2012. A delighted Bolt kisses the finish line after capturing the 200m gold medal in the final on Thursday night in Rio. (Net photo) The Jamaican, who said in February he would retire after the 2017 World Championships, has won all eight of the Olympic finals in which he has appeared. The fact I came here and executed what I wanted to is a brilliant feeling, he told BBC Sport. I wasnt happy with the time when I crossed the line but Im excited I got the gold medal - thats the key thing. Only US sprinter and long jumper Carl Lewis and Finnish long-distance runner Paavo Nurmi have won more Olympic gold medals in athletics. Lewis won nine golds between 1984 and 1996, while Nurmi also won nine between 1920 and 1928. What else can I do to prove I am the greatest? Im trying to be one of the greatest, to be among Ali and Pele, added Bolt. I have made the sport exciting, I have made people want to see the sport. I have put the sport on a different level. Bolt believed he could break his world record of 19.19 and even go under 19 seconds in Rios Olympic Stadium. The Jamaican dominated the field in Thursdays event but admitted he did not feel right in the home straight. (Net photo) So the slow time - by his standards at least - left the Jamaican gesticulating angrily as he crossed the line more than two tenths of a second ahead of De Grasse. But Bolt quickly broke into a beaming smile, celebrating with a trademark Lightning Bolt as thousands of fans chanted his name.
