The TU is a friendly boutique race in the beautiful, remote jungle, forest and hill tribes of north west Thailand.
We ensure everyone has an amazing experience when they take on the challenge of one of Asia’s toughest ultras.
The TU has a unique, friendly atmosphere before, during and after the race, and maintains the competitive edge by attracting some of the top names in world ultras.
There are two event distances:
The TU50 is The Beauty – a tough, mountainous 50km trail, but most athletes can finish, because of the generous cut off times.
The TU100 is The Beast – a very physically demanding 100km mountain ultra, that will test even the most legendary athletes!
Come and join us!
