Jamaica's Elaine Thompson-Herah successfully defended her Olympic 100m crown on Saturday, storming to victory with the second fastest time in history.
Thompson-Herah's Olympic record winning mark matched the second-fastest time in history of 10.61 set by the late Florence Griffith-Joyner.
Only Griffith-Joyner, the 1988 Olympic champion who remains the world record holder with a best 10.49, has ever run faster.
World 100m champion Dina Asher-Smith of Great Britain failed to make the final having only recently returned with a hamstring injury and has pulled out of the 200m.
