About 61.5km

61.5km is the 61.5km ultra trail at Kočevsko Outdoor Festival 2026 (Jezero Kočevje, Slovenia). The race starts on May 30, 2026.

Race strategy

Run easy on the first mountain, then go all out on the second.

  • Start easy and control your HR up to 19.9km.
  • Hold your race pace up to 34.3km, but stay in control.
  • The finish is runnable. Save your legs to run it all the way.
  • Ease into the early runnable section, then run your race pace.
  • 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–19.9km · 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 · 19.9km–34.3km · Climb of 384m, high point 1085m. 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.
  • Fade · 34.3km–44.7km · Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 44.7km–61.7km · 17.0km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
