T he highly demanding Oxfam Trailwalker will be held from November 19 to 21. The 100-kilometre trail begins at Pak Tam Chung in Sai Kung and finishes at the Po Leung Kuk Jockey Club Tai Tong Holiday Camp in Yuen Long. It aims to raise HK$26 million to fight poverty. About 1,150 teams will participate in this year's Trailwalker, a major fund-raising event for Oxfam. The four-member teams have to finish within 48 hours and raise at least HK$6,500 in sponsorship. Teams raising HK$30,000 or above this year will be given priority in registering for next year's Trailwalker. Team members must pass every checkpoint and cross the finish line together. They have to walk over more than 20 hills and mountains along the MacLehose Trail, including Tai Mo Shan, Hong Kong's highest point at 957 meters. Oxfam Trailwalker is a physically demanding event, and teams should start training three months in advance. A briefing session was held for participants recently to discuss safety tips and ways to protect the environment. The long distance of the event symbolises the long and difficult road of the fight against poverty. The message is: if we can complete this journey, it is possible for people to escape from poverty. Last year, three teams from the Hong Kong garrison of the Chinese People's Liberation Army made a triumphant debut in the event, winning the first three places. The Trailwalker started in 1981 as a training exercise for Gurkha troops in the British forces. Later it became an international fund-raising event, and participants now come from 13 countries.
