Here's a question I've been wondering about. Say you have a person who's not used to walking long distances for long periods of time. Specifically, a young woman. She's lived a relatively comfortable life, and hasn't had to do too much hard work. What kinds of aching or pains or other symptoms would she feel if she suddenly had to walk for days on end, only stopping a few times a day for breaks, between morning and nightfall. She's walking through a mountainous area, and so is only traveling about 7-12 miles per day.
So my question is basically this: what kinds of symptoms would such a person experience and about how long after beginning this kind of walking would she experience them?
Please let me know if you need more information.
