A horse pulling a carriage while walking can go 3 to 4 miles per hour. The path they take may also affect the speed of the horse.
A horse drawn carriage is not a quick mode of travel. If running without any additional burdens, the horse can go up to 15 mile an hour. If the horse walks on a clear path or a well known route, the animal can move faster. Horses also need rest. They can only cover so much ground before they need a break. If pushed to move faster, their break comes sooner. Most horse can cover up to 40 miles per day, but if they exceed that they need several days of rest before being able to use as transport again.
