The problems isn't the distance, never was, it's mostly the unpaved and uneven grounds that create the problems. A 5 kilometer walk a day, on and off, is easy to pull off, especially when treading on a well paved path and when not having to maneuver and drift through a ton of pedestrians. Those days feel like a blessing to me.

This time the issue was a badly dug up street with small hilly areas of mud and concrete, and a little path that was only a foot in width, and was somewhat "walkable". On top of that we had a ton people walking through that street, one little bump and the person with bad footing balance would end up in a 6 foot drop towards the drain pipes haha. So we surely had to tighten up and keep our feet locked on heavily.

After that it was a lot of climbing up and down through multiple stories, thanks to some "well timed" load shedding; if combined, then I probably covered over 20 stories that day, both up and down.
