About TransLantau 80

TransLantau 80 is the 80.0km ultra trail at Ultra-Trail TransLantau by UTMB 2025 (Mui Wo, Hong Kong SAR China). The race starts on November 14, 2025.

Race strategy

Hold a steady pace and save energy for every section.

  • 819m descent. Go easy, save your quads.
  • Steep 38% wall. Control your pace and stay focused.
  • The finish is runnable. Save your legs to run it all the way.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Ease into the early runnable section, save your quads on the descents until 57.1km, then run your race pace.
  • Start · 0.0km–1.2km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.2km–8.7km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Hike the steepest pitches.
  • Work · 8.7km–35.1km · Descent of 480m averaging 8%, climb of 668m, descent of 819m averaging 9%. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can. Hike the steepest pitches.
  • Fade · 35.1km–57.1km · Climb of 1027m, descent of 862m averaging 9%, high point 896m. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 57.1km–77.2km · 20.0km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
