Ang Peng Siong

Since retiring from top-level competition, Ang has devoted himself to coaching. He has worked with swimmers at all levels – from young children just learning how to swim, to national champions preparing to represent Singapore at top international competitions. He founded the APS Swim School in Singapore.

At the 2000 World Masters Swimming Championships, Ang won the 35–39 age group 50m freestyle event.

Ang was ranked fifth in a list of Singapore's 50 Greatest Athletes of the Century by The Straits Times in 1999.

At the 1986 World Swimming Championships in Madrid, Ang finished fourth in the 50 m freestyle.

Ang represented Singapore at the 1984 Summer Olympics in Los Angeles, where he won the 'B' consolation final in the 100 m freestyle. (He was not able to compete in his pet event, the 50 m freestyle, as it was not an Olympic event until 1988.)

In 1983, Ang won the 50-yard freestyle race at the NCAA Division One Swimming Championships. He was the 50-yard champion at the US Swimming Championships in 1982 and 1986, and was named an All-American for four consecutive years from 1981 to 1984.

In 1982, at the US Swimming Championships, Ang won the 50 m freestyle in 22.69 seconds, acknowledged by the swim fraternity as record time for that year. Ang represented Singapore at the 1982 Asian Games in New Delhi, and won gold in the 100 m freestyle. He was presented with the 'World's Fastest Swimmer' award for 1982.

His first major international competition was the Hawaii International Invitational Swimming Championship, an event which included many top swimmers from countries that boycotted the 1980 Olympic Games in Moscow. During the meet, Ang delighted the swimming fraternity by being the only non-American swimmer to qualify for the 50m freestyle final. As a result of his performance in Hawaii, Ang received a full athletic scholarship from the University of Houston in the United States.

Ang first represented Singapore at the 1977 Southeast Asian Games in Kuala Lumpur, where he won a silver medal in the 4 × 100 m freestyle relay.

In eight competitions at the Southeast Asian Games from 1977 to 1993, Ang won a total of 20 gold medals. He held the Asian record in the 50 metres freestyle up until 1996. His time of 22.69 seconds stood as a Singapore national record for 33 years until Joseph Schooling broke it at the 2015 SEA Games.

Ang learned to swim at the age of five , taught by his father, Ang Teck Bee (Chinese: 洪德美). The senior Ang was an athlete of note who competed in judo at the 1964 Olympic Games in Tokyo. He studied at Anderson Secondary School and Anglo-Chinese School.
