Overland Travel
While adventuring it's common to travel long distances between towns and adventuring locations. Every creature has an Overland Speed, which indicates the distance that they can travel in a day. For humans, whose Overland Travel Speed is 30 miles per day, this means they travel at a pace of about 3 miles per hour for about 10 hours on a typical day. Spending more than 10 hours traveling, or traveling at a pace faster than this, is considered a Forced March and is subject to potential penalties (see below).
In well traveled areas, it is not uncommon to have an inn or small town approximately every 25-30 miles in order to take in travelers. Out in the wilderness, however, travelers usually have to camp for the night.
Sometimes, the terrain you are traveling through can slow down your travel. See Terrain Types for more information on the different types of terrain and how they affect Overland Travel.
Forced March
When a creature travels faster than their normal Overland Speed, or for more than 10 hours at their overland speed, the creature must make a Resilience Check [DC 10] each hour. A failed check causes the creature to gain 1 point of Fatigue.
Mounts
Traveling via horse or similar mount is not much faster than foot travel for long distances, but for short time frames (less than two hours), a horse can be spurred to travel at about 6 miles per hour. For traveling longer distances or for pulling carrying carts, wagons, or carriages, most mounts travel at about the same overland speed as a human, 30 miles per day.
The main benefit of mounts is that they can pull or carry heavier loads than a human can. For that reason, they are often used more as pack animals or for pulling wagons and carts, then they are for everyday travel. Wealthier travelers will use mounts to make traveling less strenuous and exhausting.
Mounts are typically just as affected by Terrain as Player Characters, but if a mount is particularly accustomed to a certain terrain (such as a goat would be in mountainous terrain), the effect of the terrain may be reduced (or negated).
