The first semi final loaded up Natalya Antyukh and Zuzana Hejnová who pushed each other to the finish and the top two qualifying times, plus taking T'erea Brown to the top time qualifier. In the second semi Lashinda Demus had a clear lead, slowing on the way home to just exert enough effort to finish first. The final semi was the slowest led by Muizat Ajoke Odumosu's Nigerian national record, Georganne Moline and Denisa Rosolova battled for second, with Rosolova taking the other time qualifier in the process.
In the final, Demus was first over the first two hurdles, then Antyukh steadily built her lead to a full stride at hurdle 9, with Demus the closest challenger. Antyukh stuttered the tenth hurdle, opening the door for Demus to chase her to the finish line, but Antyukh held on for gold, Demus disappointed with silver and Hejnová clearly in the bronze medal position.
Antyukh's time brought her to the number 6 athlete of all time, defeating Demus who already held number 3.
