How long does it take to walk 41 miles?

A typical walking speed (not power-walking) for a healthy adult on a flat paved surface is about 3 miles an hour. So divide 711.5 by 3.

Of course, if some or all of the walk is uphill, over unpaved surfaces, through treacherous terrain, over mountains, across rivers, across crowded streets or highways, it could take much longer. And that is only the walking time. You will need to stop to rest, sleep, eat, replace worn out shoes, and take care of various bodily functions that will take up even more time. How many hours an individual can walk in a day also varies widely.
