The run solidified her place in second on the world all-time 200m list, behind only Florence Griffith-Joyner’s world record of 21.34, and Jackson’s unimpressed reaction when seeing the time was likely related to the fact she had not eclipsed that mark.

USA’s Gabby Thomas came through strongly for second in 21.81, with 100m champion Sha’Carri Richardson making it a championship to remember by taking bronze in a PB of 21.92.

“When I crossed the line and saw the time, I was like, ‘ah, I’m close,'” said Jackson. “I wrote two times on my bib today and the slow time was 21.40, and I ran 21.41. It’s a personal best, so I am grateful. I was super exhausted, I’m not feeling 100%.”
