Vietnam Trail Marathon is organised by the Danish & Vietnamese Topas Group, founded in 1973. We are passionate about the outdoors and our events are organised by adventure lovers for adventure lovers.

We founded Vietnam Mountain Marathon (VMM) in 2013 and Vietnam Jungle Marathon was added in 2017. The first VTM in 2019 completes the Vietnam Trail Series.

Our series support development in the local area as all runners long distance runners donate to charitable work via their entry fee. Over the years these donations have gone to both Sapa O Chau, a local organization that provides education and vocational training for minority youths, Operation Smile, and Newborns Vietnam. Funds are also used for projects in villages along the route, for example a school house has been constructed to vastly improve the education conditions for children living in the mountains.

Our hope is that you and your supporters and friends will enjoy this mountainous experience as much as we do while helping to contribute to its sustainable development.
