TOKYO (AP) — Elaine Thompson-Herah broke Florence Griffith Joyner's 33-year-old Olympic record in the women's 100 meters.
She crossed the line in 10.61 seconds to defend her title and lead a Jamaican sweep of the medals.
The old record of 10.62 belonged to Florence Griffith Joyner. She set that mark at the 1988 Seoul Olympics.
Thompson-Herah beat rival Shelly-Ann Fraser-Pryce by .13 seconds. Shericka Jackson won bronze.
This had been shaping up as a fast race for some time. Fraser-Pryce ran the fourth-fastest time in history at 10.63 seconds in June.
