Vietnam Trail Series by Topas

Our series is comprised of 4 popular Topas races: Vietnam Trail Marathon, Vietnam Mountain MarathonVietnam Jungle Marathon and Vietnam Ultra Marathon.



Vietnam Trail Series is the result of a love of mountain running and a fascination with Vietnam. It is organised by Topas Group, adventure travel experts since 1973.

Our Vietnam races began in 2013, when we launched the Vietnam Mountain Marathon, now one of Asia’s largest trail races with more than 5,500 runners.

The original idea was to create a race way beyond the usual trail run with a route that led runners through some of Vietnam’s most beautiful scenery populated by the countries many ethnic groups.

Our three other races, Vietnam Jungle MarathonVietnam Trail Marathon and Vietnam Ultra Marathon were founded on the same ideals.

Join us for Vietnam Trail Series races and prepare for some extraordinary adventures!



Topas has now raised over VND11billion (USD462,000) in cash for good causes. We have also given bibs worth VND2billion (USD84,000) to charity runners – these are given both to disadvantaged young people helped by Blue Dragon Children’s Foundation and also to those raising funds for our other partner charities.

Through these donations, Topas has funded the work of Operation Smile, Newborns Vietnam, Blue Dragon, Hue Help and Sapa o Chau. We also carry out local 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.
