Ultra trail running is not just an athletic endeavor; it is an epic quest of human willpower against nature. At Prenn Trail Summit 2026, the 250KM and 100 Miles categories set the benchmark for extreme endurance in Southeast Asia.
The 250KM Legend: Redefining Ultra Endurance in Vietnam
First introduced in the historic 2024 season as Vietnam’s longest competitive trail distance, the 250KM race returns in 2026 to challenge the bravest ultrarunners on the planet.
Spanning several non-stop days and nights across massive elevation gains, ancient rainforests, and misty valleys, this category pushes athletes past mental and physical boundaries. Finishing the 250KM is proof of extraordinary spirit and unbreakable dedication.
The 100-Mile Classic (~160KM)

-
Technical single tracks cutting through pristine pine hills.
-
Challenging nocturnal descents requiring focused navigation.
-
Strategic checkpoint spacing to test pacing, hydration, and nutrition.
