Rules for Travel

Overland travel follows some simple rules, and I will try to list those here

Speed 20 ft (armor) 30 ft (walk) 50 ft (horse)
Minute 200 ft 300 ft 400 ft
Hour 2 miles 3 miles 4 miles
Day 16 miles 24 miles 32 miles

The table above shows the detailed rules, however what it means for exploring hexes is:

Speed Armored Walking Riding
Time to cross 1 hex 6 hours 4 hours 3 hours

In short you can cross about 2 hexes/day unless you are on horseback, in which case you can push yourself to cross 3.
Do note that difficult terrain halves your movement speed (swamps, deep forest, etc)

All of the rules can be found here:
