Summary of research: Looking up how fast people walk. Trying to remember own experiences with hiking. Looking up how fast horses could potentially run.
My question: About how far could a reasonably fit human walk, with a bedroll and not much else on their back on smooth terrain (i.e. a main road), in a day, pausing for rests and lunch and such? About how far could one person on a horse, trying to hurry but not hurt their horse, get in the same amount of time--allowing for rests and lunch and such?
The problem is that I'm not much of a hiker or a horseperson--I can figure out how far a person walking 3 mph or a horse going 15 mph can go in a day, but I don't know how much time to allow for getting tired and going slower, or reasonable times to let a horse rest. I don't need exact times, just estimates from anyone who might be more experienced than I.
