Everytime I'm on a hike or travelling to a place far away, and I'm walking with a heavy backpack, I keep thinking: If I were not in the year 2k+, would I be able to survive a long walk to a whole other tribe or state? What about going 200Km on foot, over a few days, with your belongings in your back without a road to follow?
Is there any vivid report whatsoever of a long walk of people going to war somewhere, or really long trips, alone or in group?
In the American colonial period, Russian, French and English fur trappers and traders often covered twenty miles a day or more on foot for weeks at a time, on broken terrain in the American Northwest. Then at the end of it make camp, hunt, prepare food, sleep, and wake up and do it again. They generally lived off the land and only carried what they couldn't forage. They still had a lot to carry, even more when they were bringing back furs. They might also paddle a canoe or boat for hours upstream only making a few miles progress each day. With a heavy trading load it would often be necessary despite the hardship.
The Lewis and Clark expedition, for example, covered over seventy miles a day by river when they went with the current of the river, and ten to fifteen upstream using paddles, poles, and sail. Fur trapper Hugh Glass recorded walking over thirty miles a day as a brisk pace while trying to get through hostile Native American territory.
