LUI Kam-chi and Lo Sing-yan blazed a trail to the Sydney Olympics with one of their best-ever performances yesterday. They booked their place at next year's Games by finishing third in the men's lightweight doubles at the Asian Championships. 'They have done all that I've told them to do,' said delighted national coach Chris Perry. 'I could barely watch the race because I was so nervous. I haven't been that nervous for a long time. The race was scary.' Lui and Lo, both 26, needed a top-four finish to qualify for Sydney as the Japanese duo had already booked their place via the World Championships. With Japan racing away to win yesterday's 2,000-metre final in six minutes 29.37 seconds, the focus was on the neck-and-neck battle between China, Hong Kong, Pakistan and Uzbekistan for the next three placings. Lui and Lo had a poor start and were fifth at the half-way mark. But a strong third 500m brought them up to third and they pushed the Chinese duo all the way to the line. China clocked 6:48.39, just 0.91sec ahead of Hong Kong, with Pakistan a further 1.29 behind. Despite their success, the SAR duo will not be able to relax. 'They will race at next month's Hong Kong Championships,' Perry said. Fenella Ng Gar-loc hopes to join Lui and Lo in the Olympic squad when she seeks a top-three finish in today's heavweight singles final.
