A total of 28 records were shattered during the third round of the Hong Kong Junior Age Group Athletic Meet 2006 at Wan Chai Sports Ground last Sunday. They included one Hong Kong record, two Hong Kong junior records and 25 age-group records as rising stars showed their mettle. In boys' javelin, Yu Chi-siu broke the Hong Kong junior record for the fifth time this year, stretching his own mark to 57.25 metres, and at the same time setting a new Hong Kong record. 'I wanted to see if I could beat my previous mark. It is a wonderful feeling to see myself continuing to improve each time. It gives me great satisfaction,' said the Form Seven student from Choi Hung Estate Catholic Secondary School. Chi-siu, 19, first claimed the Hong Kong junior javelin record in the opening round of the age-group meeting in January with a throw of 51.19m. Then he improved his performance at the World Athletic Day in May, recording a distance of 51.49m. At the Hong Kong Inter-City Athletic Challenge in July, Chi-siu hurled the javelin 54.20m, followed by a throw of 55.56m in the second round of the age-group competition. 'I trained rigorously during the summer, but I will have to slow down next year because of my A-Levels. So I'm less confident about breaking my own record at the next sporting event in 2007,' Chi-siu said. He also won the boys' A1 shot put (13.69m), breaking the age-group record in the process. More than 2,000 young athletes took part in the third round of the competition organised by the Hong Kong Amateur Athletic Association. Leung Hoi-kit set the Hong Kong junior record in the boys' A1 discus with a throw of 43.88m. Wong Wing-sum was among 25 athletes who set new age-group records. Wing-sum did it for the second time this year in the girls' A1 100m hurdles with a time of 15.09 seconds. Leung Hiu-yee shattered the age-group record in the girls' A2 400m hurdles, clocking one minute, 8.91 seconds. She also won the girls' A2 100m hurdles in 14.88 seconds, although her effort wasn't good enough to break the event record.
