THE two-day Hongkong Amateur Athletic Association Youth Invitation Athletics meeting got off to a record breaking start at Wan Chai Sports Ground last night as Guangdong athletes dominated the scene. Guangdong's Li Gui-lan shattered the Hongkong women's 400 metres all-comers record with a blistering 54.12 seconds to erase the 1989 mark of 56.25 set by South Korean runner Kim Dong-sook from Seoul with Taipei junior Tseng Lau-ying a distant second in 61.74. The powerfully built Li could have run even faster had she not been required to the run the final just an hour after the earlier heats in which she clocked 57.90. Several athletes complained of the extremely short recovery period between heats and finals of the track events which led to half the field of qualifiers in both women's and men's 400 metres failing to show for the finals. Tonight's anticipated men's 800 metres clash between Police pair Roberto De Vido and Dominic Hibbel and Watson's Elite Squad's Yap Kai-tak could well not materialise if the athletes go for a fast time in the earlier heats and then miss the finals which are set for just an hour later. Guangdong's Zhang Yang set the second all-comers record of the evening when she won the women's triple jump with a leap of 12.68 metres to beat Hongkong record holder Li Chun-nei who jumped 11.88 metres. The men's 400 metres was won by Guangdong's Luo Xuming in 48.90. Hongkong's top sprinter Ku Wai-ming of the Watson's Elite Squad overcame an indifferent start to power home in 10.69 in the 100 metres and beat Guangdong's Han Chaoming by a comfortable margin with Olympian Pat Kwok-wai shaded into third with a time of 10.89. Other Guangdong men's victories went to Li Wei who cleared a good 5.00 metres in the pole vault and Zhang Xiangyang who cleared 2.09 in the high jump. The men's 1,500 metres final saw Dart's Haggai Too clock 4:05.61 to score a very easy win over Watson's Athletic Club's top juniors Simon Parsons and Chow Chi-keung who provided the best finish of the evening. Parsons clocked 4:10.39 for second place with Chow, who recently set a new Hongkong men's junior mile record, finishing just one hundredth of a second behind in 4:10.40 after the pair battled it out over the last 300 metres. Competition resumes at Wan Chai Sports Ground at 5.30 pm today.
