Four Trails

In 2012, Andre Blumberg set out to complete all four of Hong Kong’s major long-distance trails—totaling 298km and 14,500m of elevation gain—in just four days. This solo feat became the Hong Kong Four Trails Ultra Challenge, one of the toughest ultramarathons in the world. Set against the backdrop of the 2021 edition, the film traces the event’s origin, exploring the mental and physical journeys of its participants as they battle exhaustion, isolation, and the clock over an unsupported 72-hour race. Through moments of humor and heartbreak, Four Trails captures the indomitable human spirit.
