Course description

This stunning ultra route has a high percentage of trail through a wide variety of stunning landscapes.

The first 30km serves as a good warm up for the back 40km, where the majority of the climbing and descending comes.

On this 70km ultra you will venture deep into Mai Chau, far from the usual paths. The route climbs up to the fabled land of Hang Kia, where Hmong communities live not far from the border with Laos. For many years, this area was completely off the tourist map. Now you can run here and discover another side of Mai Chau.

From the highest point of the race, the route follows trails from valley to valley, each with its own stunning landscape. You will pass through an abandoned village and through ancient forest. Singe track trails weave along valley floors and traverse hill sides.

The last section brings you down to the quintessential beauty of the main Mai Chau valley. Here we will have a finish line in the heart of the community, with music, fire, food and the good trail vibes our races are famous for.

We look forward to welcoming you to Vietnam Ultra Marathon first edition on The Trails of Mai Chau.

Please read the Finish Area information here.


You must race with your own race bib. If you run with another person’s bib and you have not formally transferred that bib with the organiser, you will be disqualified and the organiser is not responsible for you on the course. 

If you run with another person’s bib you endanger yourself and others as the organiser will not have your medical records, or your emergency contact.


Top 3 VUM Runners will have mandatory kit inspections. 
Other kit inspections are carried out at random, including at the start line. 
Lack of mandatory kit will result in disqualification (DSQ) or time penalty. 

Refusal of kit check = DSQ 

Please note we disqualified runners at every event in the past year for lacking kit. Be prepared and carry what you need.

VUM 70km is a 3-point qualifying race for ITRA, an ITRA National League race, and a 100K UTMB Index race.
