Almost perfect weather conditions and excellent race management saw an all-comers record of 67 minutes and 42 seconds set by visiting Kenyan Thomas Kiprotich at the Unicef Half Marathon on Lantau island yesterday. Hong Kong record holder Chan Ka-ho also had a good race, improving his mark for the distance. Kiprotich and Hong Kong resident Stefano Passarello, winner of last weekend's Nike 10km, set a blistering pace, the pair sticking together as far as the Sunny Bay station at 6km when Passarello realised the pace was faster than he had run over the 10km distance the previous weekend. 'We were running at about 3:05 per kilometre. The pace was too hot,' said Passarello, who is improving with every race this season. The 21-year old Kenyan pulled away unchallenged to the finish line in a new Hong Kong all-comers record, taking 13 seconds off the previous mark set by former world and Olympic champion Gezahegne Abera in 2003 on the tough Brides Pool Mizuno Half Marathon route in 2003. The modest Kenyan put his win down to the excellent weather and course, but gave credit to Passarello for his company over the early stages. 'I would like to stay in Hong Kong and race some more,' said Kiprotich, who is now looking for a sponsor having arrived in Hong Kong on a visitors' visa. Hong Kong record holder for 15km and the half marathon, Chan Ka-ho, ran a far more even-paced race and settled into third place after the first kilometre. 'I didn't realise I was closing on Passarello at the end,' said Chan, who was more than happy to finish third in a new Hong Kong record of 1:09:01. The women's times were more modest with Fan Sui-pingnotching a personal best of 1:24:33, almost three minutes clear of runner-up Chan Kit yee (1:27:24) and third placed Nicky Green (1:27:55). In the 10km, Nike 10km champion Li Suet-fei repeated her win of last weekend by recording 37:53 ahead of Charlotte Cutler in 38:02. In the men's 10km, Gi Ka-man had a runaway victory in 32:55.
