Asia's biggest men's inline hockey tournament starts in the SAR today. Hosted by the YMCA King's Park Centenary Centre (KPCC) in Yau Ma Tei, the YMCA of Hong Kong 2002 Annual Invitational Inline Hockey Tournament brings together teams from Hong Kong, Japan, Taiwan, the Philippines and Singapore for the largest event of its kind in the region. More than 150 players will battle it out for the title on the concrete surface at KPCC. The puck drops for the first match at 6pm and the action continues tomorrow and on Sunday. A team from Hong Kong won the inaugural championship last year, and they are back to defend their crown under the name YMCA Hong Kong Dragons. Apart from the inline hockey action, the KPCC is opening up other facilities - the street-style skatepark and the tallest climbing wall in Hong Kong - all free. Tomorrow, free professional instruction is on hand for first-timers who are keen to scale the challenging 18-metre-high wall. There will also be 20-minute workshops for beginners at the skatepark and open jam sessions for experienced skaters, with prizes for the longest ollie and best trick. There will also be an inline skating competition. Skaters under 16 need a parent's signature to take part.
