Allen Ong

At the 2004 Summer Olympics in Athens, Ong shortened his program, swimming only in two individual events. He cleared FINA B-standard entry times of 23.49 (50 m freestyle) from the Malaysian Open Championships in Kuala Lumpur, and 51.57 (100 m freestyle) from the Southeast Asian Games in Hanoi, Vietnam. In the 100 m freestyle, Ong challenged seven other swimmers in heat four, including fellow two-time Olympians Alexandros Aresti of Cyprus and George Gleason of the Virgin Islands. He edged out Bulgaria's Raichin Antonov to take a seventh spot and fiftieth overall by 0.29 of a second, outside his record time of 52.04. In his second event, 50 m freestyle, Ong matched his forty-sixth place tie with SEA Games champion Arwut Chinnapasaen on the morning's preliminaries. Swimming in heat five, he managed to pull off a fifth-place effort in 23.52, just 0.03 of a second off his entry time.

Two years later, Ong blasted a Malaysian record of 23.62 to pick up a seventh seed in the 50 m freestyle at the 2002 Asian Games in Busan, South Korea.

Ong made his official debut at the 2000 Summer Olympics in Sydney. He failed to advance into the semifinals in any of his individual events, finishing fortieth in the 100 m freestyle (51.93), and thirty-seventh in the 200 m freestyle (1:54.53). He also placed twenty-second, as a member of the Malaysian team, in the 4 × 100 m medley relay (3:48.32).
