How can I estimate how long a hill walk will take?

Start with Naismith's Rule – one hour for every 5 km plus an extra half-hour for each 300 m of ascent – then add time for rough terrain, heavy packs or lower fitness. It’s a rough baseline, not a guarantee.

Does a heavier backpack really make a big difference?

Yes. An extra five kilos over several hours of hilly walking noticeably slows you and makes climbs feel harder, so you should factor pack weight into your time and distance expectations.

Why does the same distance feel so much harder on mountains than on flat paths?

Flat trails let you keep a steady pace, while hills, rocky or uneven ground require constant foot placement, more muscle effort and careful descent, which dramatically reduces speed even if the mileage is identical.

How Far Can You Walk?

Walking fifteen miles on flat canal paths takes less time and energy than walking six miles over steep, rocky ground. Estimating your realistic range means accounting for terrain, weather, fitness and pack weight, not just reading the distance figure.
