Sarah Healy broke the U23 National 1500m record at the World Athletics Continental Tour gold meeting in Ostrava this week.
The UCD AC athlete set a new time of 4:02.86 after an incredible performance in the Czech Republic.
Healy’s time takes three seconds of the previous record set by Olympian Sonia O’Sullivan who set the record in 1991.
The 21-year-old Healy now moves to fourth on the Irish all-time list behind O’Sullivan, Ciara Mageean and Geraldine Hendricken.
So far this season Healy has broken three U23 Distance Records. Earlier this year during her impressive indoor season Healy set new 1500m (4:06.94) and 3,000m (8:53.67) records.
