VMM 2026: Amid the Mud of Sa Pa, Vietnamese Trail Running Reaches New Heights

Rain kept pouring over the town of Sa Pa on the morning of September 18, 2026. Under the white curtain of water, thousands of runners in raincoats, carrying backpacks and trekking poles, waited silently for the starting signal. At exactly 8 a.m., the horn sounded and more than 5,300 athletes from 54 countries began their conquest of the Vietnam Mountain Marathon 2026 – the largest trail running race in Vietnam, held from September 17 to 20, 2026 in Sa Pa, Lao Cai province. But this year, the race was not only against the clock, rivals, and the limits of the human body, but also against one of the harshest weather conditions ever recorded in the history of the event. VMM is one of the first and largest trail races in Vietnam, held annually since 2026. From a small event with a few hundred participants, VMM has grown into an international sports festival, attracting more than 5,300 runners from 54 countries in 2026. This remarkable growth reflects the rising popularity of trail running in Southeast Asia. In 2026, VMM officially became part of the World Trail Majors system, a major milestone for Vietnamese sports. However, the weather itself proved to be the toughest opponent. Heavy rainfall reached record levels, turning trails into slippery mud. Steep slopes became natural mudslides, passable only with ropes. Organizers deployed hundreds of staff, installed ropes, and set up more aid stations. Dense fog reduced visibility to a few meters, forcing athletes to follow reflective markers and stay in contact with volunteers. VMM 2026 featured many distances, with the most challenging being 161 km and 100 km. The 161 km course required runners to race through the night, facing cold and extreme fatigue. Unlike road marathons, trail running demands downhill skills, pole use, and energy management. In mud and rain, every step had to be careful. The winners were expected to cross the finish line on September 19. Before that, the running community followed every development closely. Professional runners noted that bad weather could cause major surprises, as a single slip could cost minutes or force a withdrawal. Another highlight was the participation of actor Nhan Phuc Vinh, known for his passion for trail running. His determination inspired fans and brought more public attention to the sport. Under a sports analysis perspective, joining the World Trail Majors brings both prestige and economic benefits. Sa Pa bustled with thousands of international visitors, boosting local tourism and creating income for ethnic minority communities. However, organizers also faced safety and environmental challenges. Managing waste and protecting natural landscapes are essential for sustainable development. The online community showed great admiration for the athletes. Photos of runners clinging to ropes in the mud went viral, with many comments praising their perseverance. For many, the true victory was not the ranking but the courage to face the challenge. Over the past decade, VMM has become a major phenomenon. The sport has grown nationwide, with many trail races emerging. Joining the World Trail Majors will promote Vietnam's natural beauty and culture to the world. When the first runners finish on September 19, they will be welcomed with cheers and tears. Their journey, through rain and mud, will be a valuable reminder of human strength. VMM 2026 may not be the fastest race, but it will surely be one of the most memorable. The future of trail running in Vietnam is bright, and Sa Pa has proven itself a worthy destination for global champions.
