If a man can walk 25 km daily while travelling during the pre-industrial days, ridding horse he should be able to travel 100 to 200 km, right?
Figured out that's not the case. He would be travelling about 30 to 50 km horse back riding. And that riding will be basically the horse walking while carrying him on back. Not much better than travel on foot. Galloping doesn't last more than a few minutes.
Therefore daily travel in the old days was around 25 km. Regardless of transport.
