The competition was born in 1906 was banned in 1978 following a sharp deterioration in water quality and the development of ever faster shipping in Victoria Harbour, between Hong Kong Island and Kowloon Peninsula.
The event was again allowed to meet popular demand and a relative improvement of water quality in recent days, according to organizers.
On Sunday morning one thousand participants took the start under sunny skies of autumn, the best covering 1,800 meters in twenty minutes.
“It’s an event that makes sense. It brings back lots of memories for former Hong Kong, like me,” said Ronnie Wong, triple champion of the race between 1967 and 1969.
