400 metres Hurdles, Women

Date	15 – 18 August 2016
Status	Olympic
Location	Estádio Olímpico João Havelange, Engenho de Dentro, Rio de Janeiro
Participants	48 from 33 countries

Czech athlete Zuzana Hejnová had won the 2013 and 2015 World Championships and came to Rio as the favorite. She won the first semi-final but the other two semis were won by Americans Ashley Spencer (semi 2) and Dalilah Muhammad (semi 3). Muhammad had won silver behind Hejnová at the 2013 Worlds, and won the 2016 US Olympic Trials, but had done little in between. Until 2016, Spencer had been known more as an open 400 runner, winning the 2012 World Junior Championships in the 400, and taking silver at the 2016 World Indoor Championships.

Rain fell as the final started, with Muhammad going out hard and making up the stagger by the fourth hurdle. She led throughout and won gold in 53.13, followed by Denmark’s Sara Slott Petersen, who had run in second place most of the race. Spencer was fourth behind Hejnová as they came to hurdle 10, but she passed her on the run-in to take bronze, Hejnová missing the podium in fourth.
