HONG Kong athletics fans got a taste of Chinese wonder coach Ma Junren's magic when three of his talented runners from Liaoning easily won their races at the Watson's East Asian Junior Championships in Tao Po last week. Three of China's 26-strong team are from the Ma camp, which made headlines at the National Games in September when Wang Junxia and Yunxia shattered the women's world records for the 1,500 m, 3,000 m and 10,000 m events. Heading the trio of Ma runners who were in Hong Kong is 16-year-old Wang Yuan, who set world junior marks for the 800 m and 1,500 m at the National Games. Wang cruised to an effortless victory in the 800 m race in 2 min and 3.03 sec, a championship record but well below her 1:57.18 junior world mark. ''I was only aiming for the gold and wasn't primed for a really top performance here,'' said Wang, whose effort nevertheless earned her the women's Best Performance Award. ''I haven't had any systematic training leading up to this meet, but I hope to be doing more international races next year and set new world 800 m and 1,500 m records.'' Ma Ningning, the world junior 3,000 m record-holder, also swept to a convincing triumph in the 1,500 m. The 17-year-old led all the way to win in 4:14.80 with Japan's Miwako Yamanaka a distant second more than 10 seconds away. She said: ''This was actually my first official 1,500 m race and there is no comparison, but I think the time was all right. ''I do not know the reason for putting me in this race because my better distances are the 3,000 m and 10,000 m, but I just followed the coach's instructions and did the best I could.'' The remaining ''Ma Army'' runner in town was the diminutive Wang Xiaoxia, who ran an good tactical race to win the 3,000 m by more than 70 m from Japan's Akiko Suzuki. Wang posted a moderate time of 9:15.42, but it was obvious from the start that her target was the gold medal and she was not racing against the clock. She tucked behind Suzuki for the first half of the race, pulling away on the fifth lap to score without any challenge. ''My time was only fair because the first half of the race was very slow, but I'm happy to have won,'' said the 17-year-old Wang, making her international debut. ''I was a cross-country runner when instructor Ma recruited me last year and this is the first time I've ever ran on an athletic track.'' While the ''Ma Army'' runners captured all the attention, Hong Kong's star woman middle-distance runner Maggie Chan Man-yee scaled new heights in her fledgling career. She had the busiest schedule in the two-day meeting at the Tai Po Sports Ground, competing in the 800 m, 1,500 m and 3,000 m. The Heep Yunn School student was the territory's most successful athlete, winning two of the four bronze medals Hong Kong collected. She finished third in the 1,500 m in 4:28.90, beating her own Hong Kong national record by 1.61 sec. She followed it up with another third in the 3,000 m, clocking 10:01.04 to shave a massive 27.26 sec off her own national junior mark. However, the 18-year-old was not satisfied with her 1,500 m effort although it bettered the B standard for the Asian Games selection and virtually assured her of a ticket to Hiroshima next year. She said: ''My first 400 m were much too fast and ruined my chances of a really good time. I was hoping to stick with Yamanaka, but I burnt out in the first lap.'' She was a lot happier with herself in the 3,000 m race in which she totally disregarded her top rivals - Wang Xiaoxia and Suzuki - and ran at her own pace. ''Wang and Suzuki are far too good. Their best times were more than a minute ahead of me so I was only running for the bronze,'' she said, content with beating Taiwan's Chen Su-feng and Mongolia's Otgonbaiar Aligermaa. Hong Kong's two other bronzes came from Kevin Liu Chun-kee in the men's 100 m and Lee Tao in the 110 m hurdles. La Salle College student Kevin Liu ran a personal best 10.83 sec to place third behind Japan's Atsuo Narita and Taiwan's Lin Jui-hsin, narrowly edging China's Gu Nengbin out of a medal. Liu also did a personal best 22.58 sec in the 200 m in which he came a close fourth. Lee's hurdles' event only attracted three entries but nevertheless he also produced his best ever performance in taking the bronze, clocking 16.01 sec to beat his previous best by 0.68 sec.
