HONGKONG'S Sue Ross stole the show at the Singapore Triathlon when she won the women's open yesterday. The territory's Ian Rayson finished second behind world junior champion Spencer Smith of Britain in the men's open to complete a successful outing for the Hongkong team. Ross beat defending champion Helen Gilby of Singapore with ease, winning in two hours, 24 minutes while Rayson was five minutes behind the winning time of one hour, 53 minutes. Hongkong juniors Bo Bo Lee and Cheung Man-ho also shone over the full Olympic distance of a 1.5-kilometre swim and a 42-kilometre cycle ride, followed by a 10-kilometre run. Ross, competing for the first time over the distance, won despite worries over the late 3 pm start which forced her to change her flight back to the territory. She said: ''I had arrived on Friday night thinking the start would be early on Sunday. The latestart forced me to change my flight and take Monday morning off work. I hope my boss is not too upset!'' Competing in hot and humid conditions, Rayson showed his good form against a strong field. He finished almost four minutes ahead of third-placed Mohamed Rassini of Malaysia who clocked 2:02.22. The talented Hongkong triathlete was pleased with his performance and that he was able to stay in touch with Smith, although unable to pass him. ''It was a very humid day and with a short swim and long cycle it made for a very hot afternoon.'' Triathlon in Hongkong has been boosted recently with an international sportswear company injecting up to $2 million into the sport's development over the next three years. In addition, the Sports Development Board have increased the triathlon association's block grant.
