Singapore runner Dipna Lim-Prasad has clocked a new national record in the 400m hurdles by timing 60.36 seconds for a bronze medal at the Malaysian Open Track and Field Championships in Kuala Lumpur.

Vietnam's Quach Thi Lan was first in 57.74, while Wassana Winatho of Indonesia was second with 58.94.

This is the Singaporean's second national record in a month. Lim-Prasad had earlier claimed the 200m mark with 24.36sec effort at the Singapore Under-23 Open Track and Field Championships.

However, despite her fine recent form, both her 400m hurdles and 200m times are too slow to allow her to qualify for December's SEA Games. The qualifying marks are 59.64 and 24.06, respectively.
