Kerstin Ong
Kerstin Ong Jing Rong is a Singaporean athlete who specialises in the 100 metres hurdles. She holds the national record for the 100 metres hurdles, breaking it first at the 2025 Malaysian Open with a time of 13.86s. She made her Southeast Asian Games debut in 2025, clocking 13.47s in the heats of the 100 metres hurdles, and 13.85s in the final. However, both times were not recognised by the Singapore National Olympic Council as technical issues were reported with the timing system.
Early life and education
Ong joined the Singapore Sports School through "a lucky stumble" - she wanted to skip her Chinese tuition class, and it just so happened that the Singapore Sports School direct school admission trials were happening on that day. "I went competitively into this sport because I joined the Singapore Sports School, and my passion and discipline grew there," she recalled.Athletic career
