UNDISPUTED Hong Kong champion Ian Rayson will be conpeting for charity when he takes part in his first full-scale race since contracting a mystery virus during the Singapore triathlon last November. Rayson, who has been sidelined by a viral infection in his pelvis and shoulder blades for exactly one year, has entered the inaugural Carpe Diem triathlon at Discovery Bay on November 26. 'It will be interesting to see Ian doing a full race again,' said race director Chris Hanselman. 'He took part in a charity relay early in the year and he did the swim and the bike in the Everyman Triathlon last month, but this will be the first time he's done all three disciplines since catching the virus.' The Carpe Diem triathlon, also known as 'Tri for Cancer', is a memorial race for former Hong Kong international triathlete Paul Terry who died of cancer in April. The Hong Kong Triathlon Association are hoping to raise $500,000 for the Hong Kong Cancer Fund through this race, held over a relatively short course of 500 metres swim, 13 kilometres bike ride and 3.5 kilometres run. Said Hanselman: 'I'm confident we'll get a full field of 250 entries because the short course appeals to people who want to try triathlon for the first time. 'We had almost 600 entries for last month's Everyman race for which we could only accommodate 470, and many were newcomers to the sport.' There are 10 age categories for individual participants, from age 11 to 50 years and over, and three divisions for relays - open team, corporate team and school team. Organisers hope that each individual entry will raise $2,000 and teams can get $5,000.
