Hello everyone! I'm planning to make my fantasy-world as believable as possible, so I have some questions. My fantasy world is the size of a country really, and is divided into four regions. My characters will travel a lot, so I need to know more about distances. a) How many miles can a person travel by foot? b) How many miles can a person travel by horse-back? c) How many miles is Ireland, from east-west / south-north? And if you can give me more feedback on distances, I'll be very glad.
