Marcus and Julie are in Thailand now, starting to source race markers, and other supplies for the TU.

Marcus is spending the whole of May living at Cave Lodge, organising, planning and assessing the route, the checkpoints, and so on.

He will also visit the disabled children to assess progress so far and to see what supplies or other help is needed (nappies, milk, etc).

Some of the reasons why the TU is one of the most popular destination ultras in Asia:

Numbers limited to 100-200 runners, so we preserve the friendly, informal atmosphere of the event. We know all runners by name!

No corporate sponsorship. This is a boutique destination ultratrail event with no parallel anywhere in the world.

The Beast is a UTMB 5-point qualifier, and The Beauty gives you 3 points.

Invites and sponsors world-champion ultra-trail runners to keep things spicy! (Tim Olson won our 2016 100km).

Employs local hill-tribe men to prepare the course and support the runners.

Raises funds for the local hill-tribe villages and their schools (

Supports 5 local disabled kids and their families.

Holds 5 fun school-activity days in the local tribal villages (
Offers generous prize money.

Is reputed to be 'one of the toughest ultras in Asia'.

Holds a 2km village fun-run for the local kids to enjoy.

Incomparably beautiful trail that goes right through welcoming hill-tribe villages.

Excellent accommodation and food provided by the stupendous Cave Lodge guest house and other local guest houses (

World-class trips to be taken before or after the races: kayaking & caving in some of the world's most spectacular and uniques caves.

And finally, we always add in some zany twists - like this crazy guy, David Grier, who ran 1,000 km from Bangkok to the start of the TU100 - and then ran that! All for charity. Well done, David and Andrew!

Can our regular runners tell us their reasons for loving this unique event ...?

Sharing my thoughts about TU50... I did a late entry into the TU50 and I’m so glad that I did it. This is a race that well exceeded my expectations. Such a nice atmosphere at the Cave lodge. So many inspiring and nice runners there and so fun to be a part of it.
The track was awesome and brutal! Such an interesting and varied course, climbing the Heart break hill and get the view over the valleys covered in mist. Running across streams, through jungle and up and down crazy steep hills. So much positive energy at the checkpoints. So well marked trail. Everything carefully planned by Marcus, Julie and their team. Simply world class.
I have never run as long as this before, never had so much climbing and coming from cool Sweden the heat was also something new. But I could do it, and still enjoyed every minute. My leg was very tired and sore the last 15 km and it was a struggle. But I still enjoyed every meter, pushing through my imaginary paper doors and getting closer to the finish line for every step.
I planned to do my own race and stayed to the plan. Finishing was my goal and to be able to do it as the winner is just unbelievable. Thanks You all for putting this together and I really hope that I can be back at the starting line next year . /A happy winner of TU50.
