About Велика стаза

Велика стаза is the 35.5km trail race at Kozomor 2026 (Kosjerić, Serbia). The race starts on May 10, 2026.

Race strategy

Hold a steady pace and save energy for every section.

  • 430m descent. Go easy, save your quads.
  • Start easy and control your HR up to Crni vrh.
  • Hold your race pace up to 26.8km, but stay in control.
  • Control your HR on the first mountain, save your quads on the way down from it until 10.1km, then run your race pace, and go all out on the final descent from 26.8km.
  • Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.8km–20.1km · Descent of 430m averaging 10%, 5.8km of runnable trail, high point 1083m. Plus 2 more climbs. 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 · 20.1km–26.8km · Plus 1 more climb and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 26.8km–35.1km · Descent of 433m averaging 5%. Build to the finish: leave whatever you have left out on the course.

The longest climb runs 5.8km at an average 8.2% grade (478m of vertical). The longest descent runs 8.3km at an average 5.2% grade (433m of vertical). The steepest climb averages 27.5% over 0.4km.

Poles

Poles bring little benefit here: only about 6.2km of pole-friendly terrain.

Quad damage

Quad damage risk is moderate (index 23 of 100), with 40% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

  • Control your HR on the first mountain, save your quads on the way down from it until 10.1km, then run your race pace, and go all out on the final descent from 26.8km.
