The noise from the spectators reached football stadium-like decibels as Arthur Chan Hok-man crossed the finish line to win the boys' A category (born 1996) in the third leg of the Ultrakids Series at Golden Beach yesterday. Arthur, at just eight years of age, stormed home in seven minutes and 33 seconds to loud applause on the 1km run to edge out his identical twin brother Alfred into second place by four seconds. If these two boys are anything to go by the future of Hong Kong triathlon looks very promising indeed. Like most of the other 500 competitors in the third of the four-leg Ultrakids Series, the twins have the full support of their parents. James Chan, a 41-year-old computer consultant said his boys train four times a week. Twice a week they travel from their home in Yuen Long to Ma On Shan Sports Ground for distance running coaching with Watsons Athletic Club. Each session lasts for two hours. They also have swimming training twice a week in a public pool near their primary school in Tin Shui Wai. 'The boys asked me if they could enter more races after competing in a school race about 18 months ago,' said Chan. 'We didn't push them to do sport, it's been their choice entirely, and my wife and I support them as best we can.' 'The boys decided they wanted to enter the Ultrakids Series so we sent in the entry forms and got them registered. Alfred won the first race of the series in February while Arthur placed second.' The twins' mother, Ivy, was also on hand to support the boys yesterday and had a broad smile on her face as they crossed the line in matching outfits. 'I used to run when I was at school but neither my husband nor I are terribly athletic,' she said. When asked how the boys managed to combine school homework with their athletic training, she replied that she strictly limits the boys' training to a maximum of four training sessions per week. Angela Wong of the Hong Kong Triathlon Association said many of the local triathletes receive the total support of their parents, and that one of the biggest problems now facing the association is to find enough suitable race venues to accommodate the large number of participants wishing to take part. 'It's quite difficult to find ideal venues because we need a certain amount of space where we can stage our events in complete safety,' said Wong. 'The popularity of the sport has increased quite a lot in recent years, so we really need bigger venues where we can accommodate more competitors.' Alfred and Arthur were at the head of the field when the 50-strong pack hit the water for the 100m sea swim, but came out of the water just outside the top 10. Once the run got underway, however, the twins motored past the leading runners to take the first two places. Wong Yueng-chun came home a distant third half a minute later.
