assume or not to assume?

Regarding how far people can walk.

Myself & some mates done a 100km charity walk a couple of months back in the hills & we done that in just over 22hrs. That included plenty rests. Me & 2 of my mates had done loads of training leading up to it. My other mate done virtually no training. While we all felt it by the end, we still all completed it (granted we had a lot of supplies - high calorie food & plenty water). And that was only for a few quid for charity. I imagine if our lives depended on it, we could've gone a lot further & a lot longer.

My point is, don't underestimate how far some people can walk
