So adventurers sloggin trough the hills on foot hauling their loot back to town would be moving like 10 miles per day (one hex every 3 days on the big map) until they hit a road. Meanwhile the highly trained light horse unit coming up the road from Red Towers at behest of the mayor of Milham would be traveling at 45 miles per day (one and a half hex per day).
