Across the weekend of 22–25 January 2026, the Hong Kong 100 Ultra Marathon brings together runners in the remote natural terrain of Hong Kong’s Sai Kung Peninsula. The flagship race covers roughly 103 km with about 5,300 m of elevation gain, while shorter options include a ~56 km route and a ~33 km route. For the truly ambitious, the Grand Sam 192 km over all three days offers an ultra-endurance spectacle. The courses wind from Pak Tam Chung along the coast, across beaches, ancient forests, steep ridges and finally descend from Tai Mo Shan — Hong Kong’s highest peak. With ballot-based entry, world-class trail status, and scenery that blends cocos palms and granite outcrops, the event unites challenge and natural beauty in one unforgettable ultra.
