The women's 4 × 400 metres relay at the 2013 World Championships in Athletics was held at the Luzhniki Stadium on 16–17 August.

By the time Natasha Hastings broke, she had a clear lead of more than 10 meters over the Tatyana Firova from Russia in second place.

With the American team in second place coming off the turn, Francena McCorory was waiting in lane 2.

Ohuruogu found herself challenged by Floria Gueï on the backstretch but ran away from her on the home stretch for a clear third place.

In 2016, Russia's anchor runner Antonina Krivoshapka's samples from the 2012 Olympics were retested and found to contain turinabol.
