About this tool
Naismith's rule allows one hour per 5 km plus one hour per 600 m of ascent, and this tool adds your planned breaks on top. Enter distance, total ascent, and break time to get a total. It is a planning estimate — fitness, terrain, and weather can stretch or shrink it.
Frequently asked questions
What about rough ground?
Rough, muddy, or pathless ground slows you beyond the basic rule, so build in extra time.
Is this a safety plan?
No, it is a time estimate. Check daylight, weather, and daylight margins separately.
