About This Race
The Ultra-Trail Mount Yun by UTMB 70K anchors the middle distance of this UTMB World Series event in China's Zhejiang Province, offering runners a legitimate ultra experience in one of the country's emerging trail running destinations. The 68-kilometer course unfolds across Mount Yun's varied terrain, requiring the pacing discipline and nutritional planning that define proper ultramarathon preparation. As part of the UTMB World Series, this race attracts both Chinese runners and international participants seeking qualifier points for UTMB Mont-Blanc while exploring trail running in East Asia. The October timing typically delivers favorable running conditions as autumn settles over the region, though runners should prepare for potentially humid conditions that persist later into fall in this part of China. The 70K sits between the shorter 40K and the flagship 100K distances, making it accessible to runners stepping up from marathon distance while remaining manageable for experienced ultrarunners seeking a challenging weekend effort. The course demands respect but won't require the multi-day recovery of the longer format.
The route traverses Mount Yun's mixed terrain, moving between established trails, forest paths, and technical sections that characterize the region's topography. Runners should expect a course that tests both technical skills and endurance management, though specific elevation profiles vary by year as the organizing team refines the route.
As with all UTMB World Series events, the course will be marked to international standards with aid stations positioned at strategic intervals. The mixed terrain classification indicates runners will encounter variety throughout the distance, from runnable sections to more technical passages requiring careful footing.
