Kori Carter of Claremont, Calif. won the gold medal on Thursday in the women's 400m hurdles at the 2017 International Associations of Athletics Federations World Championship in London, England. Carter led a 1-2 American finish as Dalilah Muhammad of New York City, N.Y. won the silver medal.
Carter posted a winning time of 53.07 seconds. Muhammad's silver medal winning time was 53.5 seconds. Ristananna Tracey of Jamaica won the bronze medal with a time of 53.74 seconds.
Carter reached a podium spot by a full 1.13 seconds over Zuzana Hejnova of the Czech Republic, who was in fourth place with a time of 54.2 seconds.
This was Carter's first major international victory in track and field. A product of the University of Stanford, Carter did not reach the final in the women's 400m hurdles at the 2015 IAAF World Championships in Beijing and did not qualify for the American Olympic team at the 2016 Olympic Games in Rio de Janeiro.
Carter becomes the fifth American gold medalist at the 2017 IAAF World Championships, following Justin Gatlin (men's 100m), Tori Bowie (women's 100m), Sam Kendricks (men's pole vault) and Phyllis Francis (women's 400m). The gold medal for Carter will give her confidence as she prepares for the 2020 Olympic Games in Tokyo.
