I agree a man can travel a whole lot just by taking small steps on a regular basis. However, I am not sure it was that easy. - It will be easy if the map was laid out, they unlikely had any sense of where they were going those days, so to cover a hypothetical straight-ish line distance of 5500 miles they probably had to travel 10000 or maybe many many more miles - It will be easy if there were roads like now, they unlikely had very rough terrain - much denser forests, way uneven land, wild animals - They probably had to fend for food on a daily basis which would distract from an orderly journey of 10 miles a day This is not to say it could not be done, obviously it seems like it was done, and the journey probably took closer to the higher end of the extremes mentions (18 months vs 30 years) and that too mostly by happenstance.
