More than 400 people puffed and panted in the annual Walk Up Jardine House yesterday, raising $1.5 million for young people with mental illness. It was the 20th anniversary of the event, which sees entrants run up the 947 stairs to the top of the 49-storey building. Yesterday's programme involved three relays and individual races. Runners were encouraged to wear costumes, to compete for the dressing-up award. The winner of the fancy dress award was a team of five women who wore traditional Ching dynasty costumes. One of them, Monica Hong, said: 'We dressed in Chinese clothing to create a festive atmosphere.' They finished the race in about seven minutes. The fastest time for the relay was three minutes, 16 seconds. Yung Luk-kai, a 19-year-old student at Yuen Yuen Institute No1 Secondary School in Kwai Chung who won the school relay, said he would participate again. 'It's quite fun and good exercise,' Luk-kai said. 'I was very nervous waiting for my classmate. But when I saw him coming, out of breath, I knew he had tried his best.' Tracy Cheung, the winner of the business relay, said it was the second time she had taken part. Her team represented the Airport Authority. 'I run and step regularly. But I took a break yesterday for today's race,' Miss Cheung said. The $1.5 million raised will go to Health in Mind, a youth mental health promotion programme organised by the Hospital Authority and the Jardine Group.
