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.
Enter your details above and the result will appear here.
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.
