Vietnam Mountain Marathon (VMM) is part of the Vietnam Trail Series organised by Topas Travel, an adventure and travel company founded in Denmark in 1973. Today, Topas Travel is part of the broader Topas Explorer Group. 

We have been organising adventures in Vietnam since the early 90s, beginning with pioneering mountain expeditions in partnership with a Sapa family.  

Vietnam Mountain Marathon was the first ultra trail race in Vietnam. We began in 2013 with just around 200 runners. At that time, very few in Vietnam ran trails and almost all our runners came from overseas or were expats in Vietnam. 

The sport has grown incredibly among Vietnamese runners since then. We added Vietnam Jungle Marathon in 2017, then Vietnam Trail Marathon in 2019, and Vietnam Ultra Marathon in 2024.

As a team, we are passionate about the outdoors. Our events are organised by adventure lovers, for adventure lovers. 

We are proud to have had the same core management staff since we began in 2013. Our team is based in our offices in the capital, Hanoi, and in the mountain town of Sapa. Meanwhile, the Topas Group head office is in Denmark.

We place great emphasis on supporting charitable causes and we have now donated over USD445,000 to charitable work through our trail races. 

Over the years these donations have gone to Operation Smile, Newborns Vietnam, Blue Dragon, Hue Help and Sapa o Chau.

Funds are also used for projects in villages along the route, for example many school boarding houses and classrooms have been constructed to vastly improve the education conditions for children living in the mountains. You can see more about our charity work here. 

Our hope is that our runners and their supporters will enjoy the mountainous experiences we create as much as we do, while helping to contribute to good causes with us.
