About 5 LAKES TRAIL

5 LAKES TRAIL is the 20.0km trail race at Durmitor Trail Run 2025 (Žabljak, Montenegro). The race starts on July 13, 2025.

Race strategy

Run the downhill at race pace, but focus on the climb.

  • Start easy and control your HR up to the aid station at 10.0km.
  • Hold your race pace up to the aid station at 14.0km, but stay in control.
  • Final 478m descent. Save your legs to go all out on it.
  • Go easy on the first downhill, then run your race pace, and go all out on the final descent from 13.7km.
  • Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.5km–9.6km · Plus 1 more descent. Ease in: hold back more than feels necessary. The race is still ahead. Running pays off here: run wherever you can.
  • Work · 9.6km–13.7km · Climb of 397m, high point 1853m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 13.7km–20.4km · Descent of 478m averaging 7%. Build to the finish: leave whatever you have left out on the course.
