About RED COURSE

RED COURSE is the 60.0km ultra trail at Vucko Trail 2027 (Bjelašnica, Bosnia & Herzegovina). The race starts on June 19, 2027.

Race strategy

Hold a steady pace and save energy for every section.

  • Steep 43% wall. Control your pace and stay focused.
  • 902m descent. Go easy, save your quads.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Control your HR on the first climb, save your quads on the descents until 32.7km, then run your race pace, and go all out on the final descent from 53.2km.
  • Start · 0.0km–1.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.6km–18.2km · 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.
  • Work · 18.2km–28.1km · Descent of 405m averaging 15%, climb of 1033m, high point 1912m. 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. Hike the steepest pitches.
  • Fade · 28.1km–53.2km · Descent of 902m averaging 20%. Plus 1 more climb. 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. Running pays off here: run wherever you can. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 53.2km–57.9km · Descent of 332m averaging 7%. No heroics: settle back into your own effort and hold it to the line.
