Mark Williams had a point to prove. Overlooked by the selectors in an on-going dispute as to whether he's eligible to represent Hong Kong, Williams needed to win big to show he's the best local distance runner around. He proved it again. The 34-year-old Briton, who has just completed his seven-year residency, pushed himself to the limits to score another personal victory as he became the first Hong Kong runner home. 'I had a point to prove today, to be honest with you,' said Williams after completing the race in 2:37.26. 'It's the second year on the trot I wasn't picked for the Greatest Race on Earth Hong Kong team, even though I met the criteria.' 'I am annoyed by it a second time. It's the second time I became the first Hong Kong runner so I made a point again today. I am holding a permanent ID card now. I picked it up last week,' he said. 'I only started running in Hong Kong. I have done all my miles here. I train with all the Hong Kong runners and I want to represent Hong Kong,'' he said. Williams beat seasoned runner Winter Tsui by five seconds to become Hong Kong's best finisher. But he almost didn't make it. 'It was so tough the last part of the race. Last year, when we came out of the Western Tunnel, the headwind was awful. We thought it can't be like that again and it just was,' said an exhausted Williams. 'It's never easy in Hong Kong. It's concrete, it's hilly and windy and there's no one to cheer you on.' How Williams managed to pull his collective strength together to finish the race, only he knows. 'I'll tell you the inspiration came from my coach, Mark Sharp, who ran up Two IFC [on Saturday]. I kind of cramped up at the 38k mark and not doing a cliche or anything, but I thought about Mark and the inspiration came from him. I am going to buy him a beer! 'As I came to 41km I was cramping and I was looking behind me and there was no one there. Then I looked behind me again about 100 metres later and I recognised one of the Hong Kong boys. 'He was coming at me like a bat out of hell. I said to myself, 'I'm not going to get this far and become the first Hong Kong runner-up'. Somehow I found a bit more and I must have beaten him by about 10 seconds. Hats off to the lad [Tsui] because he was finishing off very well.' Although Williams was pleased in becoming the first Hong Kong finisher, he wasn't happy with his time. 'It was an awful time. I did 2:31 in Macau and 2:33 last year. I got a stomach virus from my son last Sunday and I didn't eat or drink for two days,' he said. 'I lost a lot of my strength. I didn't have much fuel left. I don't know how I managed to finish the last half of the marathon. I'm going to have a few beers to celebrate.'
