I was curious if there are any Narrators / GM's out there who have good information on the basics of overland travel measurment. Any good websites or book suggestions would be fantastic. I like using travel as a way to have my players pay attention to their micro-managing, but I'm am not much of a surveyor. I'd like to know several rates of travel for each of the following.
On foot: The characters travel by foot, covering ground for at least 8 hours
By Horseback: The characters are all on horse back and traveling for atleast 8 hours
By Boat: Travel by river, both upstream and downstream, maybe taking several different types of ship and giving them their own speeds.
By Flight: Either by mostrous mount or gyrochopter, possibly even airship / zeppelin.
After we can gather that information together I think it would benefit the game to add some basic modifiers for terrain, desired rate of travel (and the consequenses of pushing to hard), and weather.
Thanks and any information is a plus!
