Four Trails

At the time, they said it couldn't be done. In 2012, Andre Blumberg set off by himself, to run all four of Hong Kong's iconic ultra distance trails in just four days. 298km and over 14,500m of climbing later, one of the hardest ultra marathons in the world - the Hong Kong Four Trails Ultra Challenge - was born.

With the 2021 edition of the challenge as the backdrop, 'Four Trails' takes you on a journey from when the concept was first was conceived to it's current format. Under 60 hours to be deemed a 'Finisher' and under 72 hours to be a ‘Survivor’, unsupported and with an ever evolving set of rules. It takes a deep dive into the famous four trails that make up the challenge and you will both laugh and cry as the astonishing stories of those who dare attempt such a feat unfold.
