The novel is set over Eastern Europe, specifically the Balkan peninsula (though I've not decided how much of it to use) and it's set in the future, a couple of centuries after a large scale war and release of a disease to which only a fraction of people were immune to. There is effectively no collective society. And here are my questions ^^
1) How long would it take to travel long distances on foot? I searched for hiking times, and found that most people can hike 8-10 miles a day, or more if they are very fit, but I have no idea how that applies over very long periods of time, for examble travelling around 200 miles. Could people keep that continous pace, so that a journey of 20 days would be a reasonable figure?
The characters will all be used to travelling long distances, as it's an integral part of their lives, but they'll be fairly malnurished, and I'm not sure what effect that would have. Their diet is mostly meat, and low on carbs. Also, effects of things like terrain and weather would be good to know. The book is set over many years, so it's no problem if it'll take them ages.
Occasionally they'll be able to use a car, and I can obviously just decide how fast they go and work it out from that XD But I don't drive, and so I don't know if terrain/weather would have much effect on speed.
2) Because there's not much food, and living in an anarchy, the characters have very little sense of sentimentality, they'll kill and eat anything they find, be it cattle or something we'd consider as a pet animal. I don't really want them to be canibals though, and it would be nice if there was a good reason for them not eating fresh corpses. They really wouldn't have any sense of it being morally wrong or anything, but I can't find any evidence of there being bad effects to health from eating people (on the contrary, it's apparently good for you o_o) so any plausable excuse not to eat dead people would be appreciated ^_^ Oh, and how long after death would decomposition become evident? Cause that would definately put them off.
EDIT: Wow, thanks everyone! There are some really awesome replies here, they've helped me out no end. I'm also glad for the concrit of some ideas, that's really helpful. Better to hear it while I'm still in the planning stage XD But yes, again, thank you, this really has been incrediably helpful! :B
