Jamaica has broken the junior girls’ 4-by-100 metre world record to win gold at the U-20 World Championships in Cali, Colombia.

The quartet of Tina and Tia Clayton, Kerica Hill and Serena Cole blazed to 42.59 seconds in the rain of the south America country to break their own record set in Kenya last year.

Jamaica had recently ran a time of 42.58 seconds at the recently concluded Carifta Games in Kingston. However, that time was not ratified by World Athletics due to a Jamaica Anti-Doping Commission, JADCO, blunder.

Officials failed to test all four athletes on the relay team, rendering the time void under World Athletics rules.

For context Jamaica’s gold medal winning run in Cali today, would have been good enough to place sixth in the finals of the senior event at the women’s finals at the World Championships in Eugene, Oregon.
