Nguyen Si Hieu

About

Nguyen Si Hieu is one of Vietnam's leading male trail runners and a central figure in the country's rapidly expanding trail running community. He has achieved victories at the Vietnam Mountain Marathon (VMM), the most prestigious trail race in Vietnam, which takes runners through the dramatic highland terrain surrounding Sapa in the northern mountains — steep, muddy climbs, technical ridge traverses, and high-altitude descents that define the uniquely challenging character of Vietnamese trail running. A consistent top performer on the domestic circuit and a competitive presence at regional Asian trail events, Nguyen Si Hieu has helped raise the international profile of Vietnamese male trail running and is regarded as one of the country's most accomplished mountain runners.
