About HALFMARATHON TRAIL

HALFMARATHON TRAIL is the 22.0km trail race at Salomon Žumberak Trail 2025 (Perivoj dvorca Erdody, Jastrebarsko, Croatia). The race starts on June 28, 2025.

Race strategy

Run hard on the first mountain, but save energy for the second.

  • 478m descent. Go easy, save your quads.
  • Steep 32% wall. Control your pace and stay focused.
  • The finish is runnable. Save your legs to run it all the way.
  • Control your HR on the first mountain, save your quads on the way down from it until 6.8km, then run your race pace.
  • Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.3km–10.3km · Climb of 508m, high point 841m, descent of 478m averaging 13%. 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. Hike the steepest pitches.
  • Work · 10.3km–15.3km · Descent of 596m averaging 12%. This is where the race is built: steady, solid effort. This descent is hard on the legs: short steps, stay in control, poles if you have them.
  • Home · 15.3km–22.1km · 6.8km of runnable trail. Build to the finish: leave whatever you have left out on the course. Running pays off here: run wherever you can.
