The 100 meter hurdles world record of 12.21 seconds stood for 28 years until being smashed yesterday in London by American runner Kendra Harrison—who didn’t learn until about a minute after the race that she’d broken one of track & field’s most impenetrable barriers.

Harrison, who won’t be competing in Rio due to incredibly stupid qualification procedures, has consistently been among the top hurdlers in the world over the past two years. Due to what appears to be a clock error, the official time posted after Harrison crossed the line was 0.3 seconds slower than the actual, record time she’d ran—which, if you watch the race, is really an incredibly perfect display of athletic ability.

The previous 100m hurdles record had been owned by Bulgaria’s Yordanka Donkova, who set it in 1988.
