Tonight's 100 metres freestyle sprint might be her pet event, a sprint in real terms, but Hannah Wilson has already been in the pool as long as an endurance swimmer, having taken part in six gruelling races so far. No wonder she is praying she will be fresh for her tilt on lowering her Hong Kong record mark of 56.51 seconds tonight at the Hamad Aquatic Centre. And who knows, maybe even win a medal. 'Hopefully I will not have used up most of my energy and have something in reserve for my best event,' said Wilson yesterday. 'But I'm really excited about it all and enjoying myself a lot.' The 100m freestyle was originally scheduled for yesterday. But organisers decided to switch it, resulting in Wilson having to swim in the 50m free first - she qualified for the final. 'I don't know why they postponed the 100m free. But it means I have had to swim more races before my pet event,' she said. The 17-year-old Island School pupil has been in the thick of the action, having taken part in six events including winning a bronze medal in the women's 4x100m freestyle on Monday night. 'The bronze was totally unexpected This is a huge achievement for all of us,' says Wilson. She is now gunning for individual glory in the blue riband race in swimming.
