In 1970 or 1971, Chiu Sir along with Kamching brothers and sisters, established a club called Shan (Mountain) Shui (Water) Ramblers. We organized hiking excursions every Sunday exploring the natural splendor and history of Hong Kong. The largest event was attended by twelve hundred weekend hikers from all walks of life.

The efforts expended by Chiu Sir helped to promote a sense of community, and the appreciation and conservation of the natural environment. These lasting values are responsible for the proliferation of hiking trails established in the country parks since the early eighties.

In 1985, Chiu Sir organized the inaugural Sir Edward Youde Memorial Mountain Marathon Awards      to encourage hiking in the Hong Kong wilderness. The annual program was open to people of all ages. Participants were required to hike a full-marathon (43 km) or a half marathon in Sai Kung, Tai Po, and Lantau Island on three separate days. The event promoted physical fitness and acquainted many marathon runners and hikers the beauty of the country parks in Hong Kong. The marathon was organised yearly and well attended until it was suspended in 1996 due to Chiu's deteriorating health. During the course of his battle with cancer, he had the firm belief that he would recover and resume the marathon race.
