[1] The 2012 Olympic champion Natalya Antyukh could not have entered due to Russia's team doping ban.
Of the medallists from the 2012 Olympics and 2015 World Championships only Czech athlete Zuzana Hejnová was present, though her form was lacking that season.
The top-four ranked Shamier Little and Georganne Moline were beaten by Ashley Spencer and 16-year-old Sydney McLaughlin.
Eilidh Doyle, Sara Slott Petersen and Wenda Nel were the only other entrants with times under 54.5 seconds that year.
At the eight hurdle, two time world champion and the only returning medalist from 2012 Zuzana Hejnová and Janieve Russel were in a battle for bronze.
