Sze Hang-yu competes in the 200-metres freestyle at the Hong Kong Age Group Championships at Kowloon Park yesterday. But her efforts to reach the Olympic qualifying mark failed as she managed a disappointing time of two minutes and 2.75 seconds. The Olympic qualifying time is one minute and 58.33 seconds set by Fina, the world governing body. 'I felt a bit tired after a hectic schedule,' said Sze, who won a gold medal for Hong Kong at the World Cup short-course series in Dubai last month. 'I will give it another attempt [to qualify] early next year, but now I will take a three-week break.'
