How it works
This uses Naismith's rule, an old planning rule of thumb. The figures are the standard metric ones: an hour for every 5 kilometres on the flat, plus an extra hour for every 600 metres of climbing. Miles and feet are converted to these first, so 3 miles and 2,000 feet are close but not exact.
Breaks, weather, snow and a heavy pack all add time, and the rule adds nothing for going downhill. Many hikers add their own margin on steep descents.
Worked example
A hike of 6 mi with 1,000 ft of climbing takes about 2 h 26 min 21 s at a steady pace.
Questions
Does the rule include breaks?
No. Add time for rest stops, photos and lunch yourself.
Is it accurate on steep or rough trails?
It is a rough guide. Steep, rough or slippery ground usually takes longer than the rule suggests.
What about going down?
The rule adds no time for descent. Steep downhill sections often slow people down, so allow more time there.
