London rains became a part of the qualifying round, where the favorites tried to make the final with minimum effort. 52.11 was the slowest time qualifier, though Tjipekapora Herunga managed a 52.31 for the slowest automatic qualifier.
In the semi-final, the weather was better. In the first semi, Sanya Richards-Ross was matched with the defending champion Christine Ohuruogu, with only two automatic qualifiers. At the gun, Richards-Ross took off, making up most of the stagger on Krivoshapka to her immediate outside. Relaxing the backstretch but exploding on the second turn, Richards-Ross had built up a huge lead, then slowed considerably on the home stretch letting Ohuruogu gain almost all the lead back. The second semi turned into a match race between Francena McCorory and world champion Amantle Montsho, running stride for stride together far ahead of the others until Montsho dipped to place first. The third semi was a much faster affair. 2012 World leader Antonina Krivoshapka took the race out as if it were the final, making up the stagger during the first turn and coming off the turn with a huge lead. She also slowed on the homestretch and looked to struggle to hold off DeeDee Trotter and Novlene Williams-Mills. Third place Williams-Mills became a time qualifier faster than the previous two heats.
In the final, unlike the memorable race four years earlier, where Richards-Ross burned herself out building a huge lead, this time Krivoshapka had the large lead through the halfway mark and held it to the home stretch, with the three Americans spread across the track a step behind. McCorory and Krivoshapka began to struggle as first Trotter, then Richards-Ross seized the lead which she would not relinquish. Before the home crowd, Ohuruogu approached the finish line with a trademark late surge, coming from several steps off the pace to catch Deedee Trotter for the silver medal, Trotter holding on for the bronze.
