About Srednja staza

Srednja staza is the 27.0km trail race at Ozren i Devica 2027 (Serbia). The race starts on May 30, 2027.

Race strategy

Hold a steady pace and save energy for every section.

  • Start easy and control your HR up to 9.8km.
  • Steep 27% wall. Control your pace and stay focused.
  • Hold your race pace up to 25.6km, 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 25.6km.
  • Start · 0.0km–2.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.1km–9.8km · Climb of 555m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
  • Work · 9.8km–25.6km · 8.4km of runnable trail, high point 856m. Plus 2 more climbs and 1 descent. 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. Hike the steepest pitches.
  • Home · 25.6km–26.8km · Descent of 178m averaging 15%. Build to the finish: leave whatever you have left out on the course.
