About the Hiking Time Calculator
The hiking time calculator estimates walking time using Naismith’s rule: time on the flat at your walking speed plus one hour for every 600 m of ascent. Breaks, rough terrain, heavy packs and descents are not included, so add time for them.
How to use it
- 1Enter the route distance in kilometres.
- 2Enter total elevation gain in metres.
- 3Choose your fitness level and press Estimate.
Worked example
12 km with 600 m of climbing at an average 4.5 km/h takes about 12 ÷ 4.5 + 600 ÷ 600 ≈ 3 h 40 min before breaks.
How it works
Formula
Time (h) = Distance ÷ Walking Speed + Elevation Gain ÷ 600.
Common use cases
- Planning day hikes
- Checking daylight for a route
- Group trip planning
