WITH a mind vacuumed of Beijing nightmares and a heart repaired from a broken romance, Hong Kong hurdler Chan Sau-ying is ready to sweep into the record books. The 23-year-old Chan is hoping to become the first Hong Kong athlete to win a medal at a major multi-sport track and field event when she lines up for the 100 metres hurdles at the Commonwealth Games in Victoria. Armed with deep reserves of mental toughness, US-based Chan feels she has little to fear from the quality field after a successful year of competition in the United States. The communication and arts student is fondly remembered by Hong Kong fans for the tears she shed after narrowly missing out on a bronze medal at the 1990 Asian Games in Beijing. But she says she has grown up now and her recent break-up with her former boyfriend and coach, Chinese sprint hurdler Tong Li, has helped to strengthen her resolve in the pursuit for glory. ''I don't think about Beijing anymore,'' said Chan, whose personal best time of 13.14 seconds puts her in the top eight among her Commonwealth rivals. ''Sure, I was disappointed at the time, but I am not 16 or 17 anymore. I don't want to look at the past, I want to look at the future.'' Her transfer from the University of California, Los Angeles to USC this year, was the main cause of her break-up with Tong, himself a top-quality hurdler. USC refused to allow her to have a personal coach and instead she came under the overall tutorship of resident coach Jim Bush. In the end, it all worked out for the best. ''I had a lot of things in my life with studies and sport. We talked and decided that it was better for us to go our own way. ''I was quite sad at the time, but I have got over it now.'' Her main rivals in the hurdles come from Jamaica and England, but she knows that her opponents will be watching her as much as she will be wary of them. Chan's confidence stems from a productive year in which she has become one of the top four hurdlers in the States. The fact that she is from Hong Kong swells her pride. ''I'm the only girl from Hong Kong and from outside the States to get a sporting scholarship,'' she said. ''I've qualified for NCAA and also reached Division One status. I have also won a lot of races. I feel quite proud of what I've done.'' Chan's personal best time is less than half a second slower than the top-ranked woman from Jamaica, Michelle Freeman, who boasts a time of 12.77 seconds. She knows that she may have to run a sub-13 second time for the first time in her life if she is to be among the medals. Chan is Hong Kong's best hope to reach a final or win a medal in the track and field competition. Distance-runner Maggie Chan Man-yee, despite improving tremendously throughout the year, can only realistically look towards the women's 1,500 metres to make an impact. Her best time of four minutes 25.10 seconds is the 11th fastest from the 16-woman field. Maggie Chan's 800 metres time of 2:17.47 is the 24th fastest, while she is ranked 17th out of 19 in the 3,000 metres with a time of 9:46.43. Long-jumper Li Chun-nei is ranked 19th in her field, her best effort being 5.89 metres. She is hoping to break the Hong Kong record of 6.03 metres.
