Elaine Thompson-Herah just became the first woman to win a "double-double" in Olympic track and field's fastest races. The Jamaican sprinter nabbed gold in both the 100-meter and 200-meter races in Tokyo, repeating her two wins in the same contests at the 2016 Rio Olympics.

Jamaican sprinter Elaine Thompson-Herah broke Florence Griffith Joyner's 33-year-old Olympic record in the women's 100 meters. Thompson-Herah set the new record of 10.61 seconds on Saturday as she took home gold in Tokyo. Griffith Joyner, also known as Flo-Jo, had held the record of 10.62 since the 1988 Seoul Games.
