Jamaica’s under-20 girls’ 4x100m world record at the Carifta Games in April will not be ratified by track and field governing body, World Athletics.

Jamaica’s 42.58-second clocking has been rejected by World Athletics because one of the four members of the quartet of Serena Cole, Tina Clayton, Brianna Lyston and Tia Clayton was not drug tested at the completion of the race on April 17 in Kingston, Jamaica.

However, the Jamaica Anti-Doping Commission (JADCO), has questioned the reasoning of World Athletics, saying the ‘untested’ athlete had been tested a day before the unaccepted World Record-run.

In a release today, JADCO said the body will adjust, ensuring it tests athletes after achieving world marks, regardless of the frequency of tests.

According to JADCO, a test of the athletes, according to World Anti-Doping Agency protocols, is considered in-competition testing, no matter which day of the competition the test occurs.

Despite this, Jamaica still holds the Under-20 world record, which set they set at the 2021 World Under-20 Championships in Kenya in August of 2021.

That team, made up of Cole, Tina and Tia, and Kerrica Hill, established a time of 42.94.
