About Bukulja Trail

Bukulja Trail is the 15.0km trail race at Bukulja Trail 2025 (Aranđelovac, Serbia). The race starts on April 12, 2025.

Race strategy

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

  • 312m descent. Go easy, save your quads.
  • Start easy and control your HR up to Kuselj.
  • Hold your race pace up to 10.2km, but stay in control.
  • Go easy on the first downhill, save your quads on the descents until 3.9km, then run your race pace.
  • 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–9.1km · Descent of 312m averaging 8%, high point 693m. Ease in: hold back more than feels necessary. The race is still ahead. 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 · 9.1km–10.2km · Plus 1 more descent. This is where the race is built: steady, solid effort.
  • Home · 10.2km–14.9km · Climb of 334m. Build to the finish: leave whatever you have left out on the course. Climb by heart rate or breathing, not pace.
