Adeleke smashes Irish 400m record yet again in Austin

Rhasidat Adeleke has smashed her own Irish record over 400m and posted the fourth fastest time in the world this year at the NCAA Championships in Austin.

Only last month in Florida, Adeleke broke the 50-second barrier for the first time, clocking a new national record of 49.90 in finishing second behind Britton Wilson.

This morning, Adeleke brought the record down once more, posting a time of 49.54 to win her quarter-final ahead of Rosey Effiong.
