Three school records fell on Friday at the Schools National Track and Field Championships, with Singapore Sports School's (SSP) Tia Louise Rozario breaking two long-standing records at Bukit Gombak Stadium.

The 14-year-old registered a 5.56m leap which saw her clinch the B Division Girls' long jump title. She fell the division's record of 5.33 set by Chua Eng Mui 35 years ago and also eclipsed the national schools mark of 5.53 written by Koh Hong Phang back in 1973.

For two hours, the afternoon session at Bukit Gombak Stadium was delayed due to bad weather but Tia allow never allowed proceedings to distract her.

Said the 14-year-old: "I was surprised because I felt a little down today after the rain. But I kept focused because there was always a possibility of the final continuing."

Megan Low of SSP and Megan Ang of Nanyang Girls' High School both jumped 4.96, but the former finished second on countback.

In the A Girls final, Lynette Lim of Victoria Junior College jumped 5.43 to emerge victorious, falling the division record of 5.40 set by her alumnus Lynette Chen in 1991.
