BUDDING sprinter Wong Man-lung, who last month broke a 42-year-old inter-school record, will be aiming to make his mark on the international arena, when he takes part in the Thailand Open track and field meeting this weekend. Man-lung clocked 10.74 seconds in winning the 100 metres at the Division One inter-school athletics championships last month to clip 0.6 of a second off the long-standing mark set by Stephen Xavier in 1953. The 18-year-old Kowloon Wah Yan College pupil is aiming for a personal best effort in Thailand, where he will also compete in the long jump. Two other highly promising youngsters making their international debut at the Thailand meeting are high jumper Wan Tat-yung and sprinter Tang Hon-sing. Tat-yung is only 16, but he has shown tremendous potential with a personal best jump of 2.04 metres, while 17-year-old Hon-sing is a specialist in the 100 m and 200 m. Hon-sing's best time for the 100 m is 11.12 sec and his top effort for the longer sprint is a commendable 22.25 sec. Another teenager attending the Thailand meeting is woman sprinter Wan Kin-yee, holder of the Hong Kong junior records for both the 100 m and 200 m events. Nineteen-year-old Kin-yee's record for the century dash is 12.06 sec and her 200 m mark is 25.18 sec. Hong Kong's woman middle distance running star Maggie Chan Man-yee kept the territory's colours flying at the Bendigo Easter Fair Dragon Mile in Australia with a second-placed finish. The 19-year-old Heep Yunn School pupil clocked four minutes and 58 seconds despite a foot injury to take the runner-up prize.
