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 stops and allowances for rough terrain, weather, heavy packs, fitness and time-consuming descents. It is a rough baseline, not a guarantee.

Does a heavier backpack really make a big difference?

It can. The effect depends on your fitness, body size, terrain and the load, but extra weight over several hours of hilly walking increases effort and may slow you, so 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 and rocky or uneven ground demand more climbing effort, careful foot placement and controlled descent. That can reduce speed substantially even when the mileage is identical.

How Far Can You Walk?

Walking fifteen miles on flat canal paths can take 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.
