Local swimmer Maximillian Ang clocked 4min 48.13sec in the men's 400m individual medley event at the Singapore National Swimming Championships (SNSC) on Friday evening, setting a new national Under-14 record for the event.

His time beats Dylan Koo's old mark of 4:49.51, set in March last year. Maximillian, 13, finished fourth in the event behind Malcolm Low (4:33.80), Darren Chua (4:39.18) and Dylan (4:41.38).

Said the Swimfast Aquatic Club swimmer: "It was a very tiring swim. I was exhausted swimming the breaststroke, which is usually my strongest stroke."

Before clocking a new record, Maximillian had also swam a new personal best in the morning heats, a 4:50.31 to make him the fastest qualifier for the final.

Meanwhile, in the night's other events, Quah Ting Wen and younger brother Zheng Wen put themselves in contention for next June's SEA Games when both met the qualifying marks for the biennial event.

Ting Wen, 22, clocked 2:01.46 in the women's 200m freestyle to finish first, while Zheng Wen was tops in the men's 100m butterfly with a 53.63s.

The SNSC is one of three qualifying meets designated by the Singapore Swimming Association.

Swimmers can also qualify through time trials in February and at the Singapore National Age Group Swimming Championships in March.

The fastest two qualifiers for each event will earn berths at the SEA Games next year.
