"298km nonstop across all four Hong Kong trails. 14,500m vertical."
A nonstop 298km traverse of all four Hong Kong trails.
The Course
A 298km non-stop traverse of all four major hiking trails in Hong Kong: the MacLehose Trail (100km), Wilson Trail (78km), Hong Kong Trail (50km), and Lantau Trail (70km). Runners navigate steep jungle ridges, exposed mountain passes, urban sections through Kowloon, and remote coastal paths. The cumulative elevation gain exceeds 14,500m — equivalent to climbing from sea level to Everest Camp 3 and back, twice. Aid stations are self-arranged; this is an unsupported challenge where runners carry their own food and manage their own logistics across one of the world's most vertical cities.

Lore & Trivia
The Four Trails Ultra Challenge was born from Hong Kong's obsessive hiking culture — a city of 7.5 million crammed into vertical jungle where trail running is practically a national sport. The challenge links all four of Hong Kong's official long-distance trails into a single continuous push. It's self-supported, self-navigated, and deeply respected in the Asian ultra community. Finishers earn near-legendary status in Hong Kong's tight-knit trail running scene. The 60-hour time limit is generous on paper but brutal in practice — the humidity, vertical gain, and urban navigation sections through Kowloon at 3am destroy even experienced ultrarunners.
- ▸ 298km and 14,500m of climbing nonstop.
- ▸ Links all four of Hong Kong's major hiking trails.
- ▸ Sleep management is part of the challenge.
Four trails, 298 kilometres, 14,500 metres of climbing. And you do it with no support in the most vertical city on earth.
