More than 800 athletes from across Asia will converge on Siu Sai Wan Sports Ground this weekend for two days of international track and field competition in the Hong Kong Inter-City Athletics Challenge. Teams from eight countries and five mainland Chinese cities will undergo acclimatisation and final training at the impressive sports facility today in preparation for the competition, which starts tomorrow at 2pm. Teams from China, South Korea, Malaysia, the Philippines, Singapore, Thailand and the United States will take part in the two-day event. Sydney 2000 Olympian Chen Shu-chuan is listed to run in both the women's 100m and 200m sprints, and will be one of 97 competitors from Taiwan. Chen, 27, has a personal best of 11.47 seconds for the 100m and 23.47 seconds for the 200m, both of which are well inside the Hong Kong records. Teammate Chou Yi-chen, national record holder in the men's javelin competition with a personal best throw of 76.18 metres, will also compete. The 21-year-old will also be part of the Taiwan team for this year's East Asian Games in Macau. Malaysia's Lee Hup-wei has recovered from an ankle injury and will be hoping to improve on his personal best of 2.15m in the men's junior high jump. The Form Five student claimed the under-18 national schools record in Penang last month, a feat that earned him a place in the national squad for the SEA Games in Manila this year. Malaysia will be represented by 17 athletes, including M. Vadivellan, who also qualified for the SEA Games at the Penang meet after clocking 3:55.21 in the 1,500m, the first Malaysian athlete to record a sub-four minute time this year. A number of Hong Kong athletes will be out to stem the expected tide of overseas medal winners, including star sprinter Tang Yik-chun and the ever reliable 'Athletic Queen' Wan Kin-yee. National 110m hurdles record holder Tang Hon-sing has also shown good form coming into the meet, and may well lower his Hong Kong record of 14.32 seconds if he's pushed all the way by quality opposition.
