For anyone who has seen the 4X400-meter running mixed relay final from the World Athletic Championships in September 2019 (World Athletics) the differences in athletic performance between men and women are blatantly obvious. A woman, Justyna Święty-Ersetic from Poland, was in the lead when she took the baton for the final lap of the race with a 5 second lead over the closest competitor. A 5 second lead in a 400m running event should be nearly insurmountable. However, on this final leg of the mixed sex relay all of the other runners were men. Within 150 meters of the baton exchange Michael Cherry had passed Święty-Ersetic, and by the finish line Święty-Ersetic had fallen to 5
Excellent, well written and documented. Thank you.
