Hiking Time Calculator
How long will that trail actually take? This calculator uses the classic Naismith's rule — one hour per 5 km plus extra time for climbing — so you can plan your hike, daylight and rest stops realistically.
How to use
- Enter the total route distance in kilometres.
- Enter the total uphill climbing (ascent) in metres.
- Your estimated walking time appears instantly.
Tips
- Naismith's rule assumes a fit walker on easy ground — add extra time for rough paths, heavy bags or hot weather.
- Plan to finish at least an hour before sunset so you are not rushing downhill in the dark.
- Steep descents often take nearly as long as climbs, so do not ignore the way down.
Note
Uses the classic Naismith rule at 5 km/h plus 10 minutes per 100 m of ascent. It assumes a reasonably fit walker on decent paths — add time for rough terrain, heavy packs, heat, breaks and descents on steep ground. Estimate only — not medical advice.
Frequently Asked Questions (FAQ)
How does the hiking time calculator estimate the time?
It uses the Naismith rule: about 5 km per hour on flat ground plus 10 minutes for every 100 metres of ascent.
What inputs does the hiking time calculator need?
The total route distance in kilometres and the total ascent in metres. The estimated walking time appears instantly.
Does the estimate include rest breaks?
No. The estimate is pure walking time for a reasonably fit walker on decent paths; add extra time for breaks, rough terrain, heavy packs and steep descents.
Is the estimate exact?
It is an estimate only, not medical advice. Steep descents can take nearly as long as climbs, so do not ignore the way down.
