Race strategy

Hold a steady pace and save energy for every section.

  • 302m descent. Go easy, save your quads.
  • Start easy and control your HR up to 23.6km.
  • Hold your race pace up to Dulenski Crni vrh, but stay in control.
  • Go easy on the first downhill, save your quads on the descents until 17.4km, then run your race pace, and go all out on the final descent from 55.8km.
  • 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–23.6km · Descent of 302m averaging 5%, descent of 269m averaging 16%. 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. 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.
  • Work · 23.6km–31.6km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
  • Fade · 31.6km–55.8km · 9.4km of runnable trail, high point 900m. Plus 1 more climb and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 55.8km–57.8km · Descent of 248m averaging 12%. No heroics: settle back into your own effort and hold it to the line.
