A tsunami survivor, a disabled human rights lawyer, a former cancer patient and a doctor have joined together to cheer on walkers in this year's Oxfam Trailwalker, which starts tomorrow morning. The four gave their backing to Hong Kong's largest fund-raising sporting event yesterday and urged the public to support hikers as they tramp the 100km MacLehose Trail from Sai Kung to Tuen Mun. Lalith Jayasekera, an amputee who was swept from his wood-carving workshop in Sri Lanka by December's tsunami, is no stranger to this year's theme, 'Never give up'. He survived the giant wave by clinging to a tree and managed to limp home despite losing his crutch. With the help of Oxfam Hong Kong, he got a new prosthesis and has since reopened his workshop. He now carves pieces commemorating the disaster. 'The tsunami destroyed our homes and livelihood, but it didn't destroy our faith,' he said. 'Villagers believe that with determination and team spirit, we can rebuild our lives. Maybe the slogan 'never give up' applies to us all.' Louisa Cheng Wan-lan overcame colon cancer and an arduous recovery to complete last year's Trailwalker and win the State Street Overcoming the Odds Award. 'The Trailwalker isn't about competition or the challenge but charity,' she said. 'I hope Hong Kong people will come out and make a difference.' Born with abnormalities in her hands, legs and hips, Thanjua Nawaratne has suffered hardship and discrimination throughout her life in Sri Lanka. As a lawyer, she has worked tirelessly for inclusion and access for disabled people in the rebuilding of the nation, with some success. 'Funds raised at events like these are helping so many people,' she said. Lo Wing-lok, a nine-time veteran of the 100km hike along the MacLehose Trail, saw at first hand the good work his sweat and blisters funded when he travelled to India with Oxfam Hong Kong in the wake of the tsunami. 'I'm joining Trailwalker because I really want to do more to support Oxfam's emergency relief and poverty alleviation work,' the doctor and former legislator said. The 1,040 teams competing in this year's event aim to raise $19 million for emergency relief and poverty alleviation projects in Asia and Africa.
