I frequently find myself having to calculate how far away things are when I'm writing. "How long would it take him to walk there? Can a horse run that far? Who would get there first?"
This is a reference for myself, but I figured you could probably use it too. The numbers here are averages. Actual speeds and endurances will vary.
|Human||Horse w/ Heavy Load||Horse w/ Light Load|
|Walking Speed||5 kph|
|Distance Traveled in a Day (8 hours)||40 km|
|Hurried Speed||10 kph|
|Distance Traveled (1 hour)||10 km|
|Running Speed||24 kph|
|Distance Traveled (5 minutes)||2 km|
Walking Speed: A basic, slow walk that can be maintained for hours at a time.
Hurried Speed: A jog or canter that can be maintained for about an hour.
Running Speed: A sprint or gallop that cannot be maintained for more than a few minutes.
Again, these are just averages. There are horses that can gallop at speeds of 70-80 kph (40-50 mph), people can be forced to walk for more than 8 hours a day (with consequences), and some folks couldn't maintain a jog for longer than 30 seconds (*raises hand*). But for me, these averages are useful in figuring out how far apart things are in my worlds, among other things.
Feel free to correct my numbers, if you know better, or to request other means of transport for me to add.
