The Müller Anniversary Games in 2016 saw arguably one of the greatest performances of all time as Kendra Harrison broke the women’s 100m hurdles record with a faultless performance under the lights in London.

Harrison had already underlined her credentials in the event as she set a meeting record of 12.40s to qualify fastest for the final on Friday night.

The American had also, just a few weeks earlier, moved herself up to second on the all-time world list courtesy of a 12.24s run in the United States at the Eugene Diamond League but showcased her ability to produce perfect hurdling as she cut the tape in world record time.

The stadium clock had originally stopped at 12.58s as Harrison dipped underneath the beam on the finish line, leading her to casually walk back around the track following what to her was initially a routine win.

When the time was revised down to 12.20s, an emotional Harrison dropped to her knees on the track as the magnitude of what she had just achieved sunk in.

Her time revised Bulgarian Yordanka Donkova’s effort of 12.21s set back in 1988 in Bulgaria and sent the crowd inside the London Stadium into raptures.
