In the women's 100m, all eyes were on Shelly-Ann Fraser-Pryce, who was seeking to become the first woman in track to win three Olympic gold medals in a row. But it was her fellow Jamaican Elaine Thompson who ran away with gold.
Thompson, 24, turned what was supposed to be one of the most competitive races on the Olympic programme into a stroll. Running even at the halfway mark with Fraser-Pryce and Tori Bowie of the United States, Thompson pulled away over the last half and defeated Bowie with a bookshelf-sized slice of daylight in between, finishing in 10.71 seconds
Fraser-Pryce led the women's final early, but faded, and settles for a bronze medal to go with the green-and-yellow, Jamaican-flag hairdo she worked up for her turn as her country's flagbearer at the opening ceremony
