Two national Under-14 swimming records, lasting two decades, belonging to two of Singapore's former star swimmers finally crumbled on Wednesday night.

Tan Jing-E smashed Joscelin Yeo's 200m individual medley (IM) mark clocked at the 1993 SEA Games trials (2min 23.42sec) with a 2min 22.58sec swim at the 45th Singapore National Age Group Swimming Championships.

The meet was held at the Singapore Sports School.

Darren Chua was another record breaker when he was timed 1min 56.21sec in the 200m freestyle final. That broke a 20-year mark held by Sng Ju Wei, who was timed at 1:56.71 at the 18th South-east Asia Age Group Swimming Championships in 1994.

He also rewrote his own U-14 mark in the 200m IM, shaving more than two seconds off his previous mark with a time of 2min 10.83sec.

It was not just the Singapore age group records that fell.

Quah Zheng Wen, 17, rewrote his own national mark in the 50m backstroke with a time of 25.92sec, shading his own previous time of 26.15sec set in 2012.
