Course description

The Vietnam Ultra Marathon 25km starts and finishes in Mai Chau offering a diverse route with a high percentage of trail.

The first section of 25km trail follows the same course of 70km over the hill to Te village (CP1). You then have a hard but rewarding climb up to Xe village. From Xo village, you will hit a tough climb across the hillside to join the course of 70km, 50km.

The last beautiful section is full of variety and 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 25km is a 1-point qualifying race for ITRA, an ITRA National League race, and a 20K UTMB Index race.
