About 13km

13km is the 13.0km trail race at Trail na Mljetu 2027 (Croatia). The race starts on May 1, 2027.

Race strategy

Short race: go all out.

  • Hold your race pace up to the aid station at 7.9km, but stay in control.
  • Ease into the early runnable section, then run your race pace, and go all out on the final descent from 7.9km.
  • Start · 0.0km–2.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 2.1km–7.9km · Climb of 252m, high point 245m. 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 · 7.9km–12.8km · Descent of 322m averaging 7%. Kick for the line: give it everything you've got.
