In what was a season-ending competition for several of the Caribbean athletes competing at the meet, Clayton ran a meet record 53.89 to win the 400m hurdles in a comfortable fashion over Viktoriya Tkachuk, who ran 54.97.
An obviously leg-weary Janieve Russell, the 2022 Commonwealth Games champion, was third in 55.04.
Clayton wasn’t even aware that she had broken the 54.14 meet record set by Diami Pernia set 22 years ago.
“I actually did not know what the meeting record was,” said Clayton, who just missed out on a medal at the Commonwealth Games in Birmingham, England.
“I just wanted to run my last race and to get a good race and I did just that.
“The weather did not affect me, really, because I was in a zone and I just wanted to come out here and compete, it is my last one.”
Cofil, who broke 50 seconds in her last two races, didn’t need to in order to claim victory in the 400m.
