Flat walking 2.4 h · Climb extra 1 h

Total hours 3.4 h

How it works

  1. 1Flat time = 12 / 5 = 2.4 h
  2. 2Climb time = 600 / 600 = 1 h
  3. 3Total = 2.4 + 1 = 3.4 h = 3h 24min

Reading the result

Naismith (1892): 1 h per 5 km plus 1 h per 600 m of ascent, regardless of how the climb is distributed. Rough terrain or a heavy pack: drop to 4 km/h. Use it to judge daylight needs and turnaround times.

The classic rule covers moving time only: add 10-15 min per hour for breaks. Descent is ignored in the original rule (Langmuir's variant: +10 min per 300 m of steep descent). Fitness, weather and trail condition can shift results by ±30% — treat it as a planning baseline, not a guarantee.
