Cow Mountain at 2,300m and rice terrace valleys — a 50km for true mountain lovers
A demanding 46.7km ultra with 2,800m of gain through the hidden valleys and high ridgelines of Sapa. The course climbs directly to Cow Mountain at 2,300m via singletrack through pine forests and grasslands — one of the most spectacular viewpoints in Vietnam — before a technical descent into Ta Phin village. Riverside trails, the 31 Bridge checkpoint, steep village paths, and a final Mount Silverstone ascent complete a race for those who truly love the mountains. Part of the World Trail Majors Short Series, ITRA 2-point qualifier, and 50K UTMB Index race.
