Competitors in Sunday's Mizuno Half Marathon at Tai Mei Tuk will have an added incentive to excel with the Hong Kong Amateur Athletic Association (HKAAA) donating funds to the Asian tsunami appeal according to performance. The HKAAA will donate $20 for each runner who successfully completes the hilly 21.1-kilometre event, which also doubles as the Hong Kong Half Marathon Championships. Most of the race is on Bride's Pool Road but also takes in an often windy lap of the dam across Plover Cove Reservoir. The HKAAA will extend the donation for runners who manage to reach the gold, silver or bronze standards, or if they beat the two invited runners from Japan. They hope to raise $100,000. A $100 donation will be made for male runners finishing under 1:45:00 and for women finishing in two hours. This sum goes up to $150 for times of 1:30:00 and 1:45:00 respectively and to $200 for males finishing under 1:25:00 and females under 1:40:00. A $1,000 donation will be made for each runner who completes the course faster than the Japanese competitors of the same gender. Ken Takafuku, director of Ichikawa Sangyo, the Mizuno distributor in Hong Kong, said his company fully supported the HKAAA incentive. 'We're delighted that the HKAAA has chosen our event to help fund-raising for the tsunami appeal,' said Takafuku. 'We've once again received a huge response for entries and we have a capacity field of 2,000 runners, which should mean that quite a lot of money is raised.'
