About Velika staza

Velika staza is the 36.0km trail race at Ozren i Devica 2027 (Serbia). The race starts on May 30, 2027.

Race strategy

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

  • Big early climb with 1010m gain. Hold your pace, save your legs for later.
  • Start easy and control your HR up to Ostra cuka.
  • Hold your race pace up to 34.5km, but stay in control.
  • Control your HR on the first climb, then run your race pace, and go all out on the final descent from 34.5km.
  • Start · 0.0km–2.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.3km–21.3km · Climb of 1015m, 6.9km of runnable trail, high point 1173m. 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 · 21.3km–34.5km · 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 · 34.5km–35.7km · Descent of 178m averaging 15%. Build to the finish: leave whatever you have left out on the course.
