Vietnam Jungle Marathon (VJM) 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.  

The Vietnam Trail Series began with Vietnam Mountain Marathon in 2013. This was the nation’s first ultra trail. We then added Vietnam Jungle Marathon in 2017. Today our series also includes Vietnam Trail Marathon (founded 2019).


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. 

We place great emphasis on supporting charitable causes and we have now donated over USD400,000 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 a school boarding house 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.
