I think I read that heroic characters can walk for 10 hours in a day at about 3 miles per hour - or maybe it is faster than that in less time - but they suggested that a 30 mile walk is a lot for a day - especially with carrying a lot of gear.

It might be faster by horse, or maybe you would just carry more stuff.

Of course rough terrain would slow people down... mountains and forests and swamps, oh my!

Google land movement in D&D... some previous editions had crazy charts for that stuff...
