Kenyan runner Faith Kipyegon broke away from the pack to claim gold in the women’s 1500m final on Tuesday.
After a cautious start the pace increased in the latter stages of the final in Rio, when the 22-year-old pulled ahead alongside Genzebe Dibaba of Ethiopia, with the rest trailing behind.
Kipyegon ended with a time of 4:08.92 ahead of Dibaba on 4:10.27 for silver, while Jennifer Simpson of the United States took bronze with a time of 4:10.53.
As the two Africans opened up a massive lead, a second race developed for bronze, with Simpson crossing the line just ahead of fellow American Shannon Rowbury.
Laura Muir of Great Britain was alongside the two medalists as they began to pull away, but she pushed herself too hard trying to keep up with them and ended up falling behind and finishing seventh.
