Hong Kong Four Trail Ultra Challenge

Confront the ultimate unsupported endurance trial in Asia: the Hong Kong Four Trails Ultra Challenge (HK4TUC), a legendary 298km solo battle across Hong Kong's four major trails with 14,500m of ascent, starting in Tuen Mun on Monday, 19 January 2026. This invitation-only, non-commercial event demands runners complete the MacLehose, Wilson, Hong Kong, and Lantau trails in reverse sequence within a brutal 60-hour cutoff, entirely self-supported on the trails with a strict 18-hour limit for the first leg. Founded on a philosophy of extreme hardship and self-reliance, it strips ultrarunning to its raw core—just a runner, a heavy pack, and a near-impossible test of physical and mental fortitude against the clock.

More than a race, the January 19th challenge is a pilgrimage for those who seek meaning in suffering and the thrill of attempting the impossible. With no public roster, pacers, or drop bags allowed, and recognition only as a "Finisher" or "Survivor," it represents the purest, most formidable expression of solo endurance in the sport, where success is measured solely by one's own resolve against Hong Kong's unforgiving terrain.
