The Hong Kong 100 course starts in Pak Tam Chung on the east side of Hong Kong's New Territories and winds its way west along coastal paths, across beaches, through ancient villages, over hills and through valleys before finishing after the descent of Tai Mo Shan, Hong Kong's highest peak (at 957m). The 103km journey climbs over 5,300m and much of the climbing is in the second half of the course, so it's important that runners pace themselves sensibly over the first half, leaving something in reserve for the hillier sections later on.
