About PLAVA STAZA

PLAVA STAZA is the 40.0km trail race at Vučko Trail 2025 (Bjelašnica, Sarajevo, Bosnia & Herzegovina). The race starts on June 13, 2025.

Race strategy

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

  • Start easy and control your HR up to 10.3km.
  • Hold your race pace up to 34.8km, 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 34.8km.
  • Start · 0.0km–1.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.4km–10.3km · 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. Running pays off here: run wherever you can.
  • Work · 10.3km–34.8km · Climb of 308m, high point 1749m. Plus 1 more 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.
  • Home · 34.8km–39.6km · Descent of 318m averaging 7%. No heroics: settle back into your own effort and hold it to the line.
