HONG Kong is set for a record-setting athletics treat tomorrow afternoon when the classic Watson's International Invitation Mile is run at 3.10 pm on the newly-resurfaced Wan Chai Sports Ground track. The race has the makings of Hong Kong's first ever sub-four-minute mile because sponsors Watson's Water have flown in seven international class middle distance men from around the world who have all have run under four minutes. With Watson's offering US$3,000 for a sub-four-minutes race winner it will be every man for himself. The race is the feature event of this year's Watson's two-day Hong Kong Open Athletics Championships organised by the Hong Kong Amateur Athletic Association (HKAAA) which starts at 8.30 am today. Ireland's experienced Marcus O'Sullivan starts as favourite from British pair John Mayock and Tony Whiteman. The Philadelphia-based O'Sullivan, who has a very fast three minutes 50.94 seconds mile to his credit, is confident the record can fall. 'We are definitely going for sub-four minutes and even though there is no rabbit in the field the pace will be on as all the runners know what is needed,' he said. Whiteman too was confident the pace would be on. Mayock is also well in with a chance having run 3:51.89 earlier this year in the Weltklasse Zurich Mile. But last night he was looking for a pair of racing spikes after only bringing his road racing flats. The other sub-four men are American Terrence Hetherington, Australians Shaun Creighton and Nigel Adkin, and New Zealander Hamish Christensen.
