Overland Travel

13th Age isn't a game built around the 5-foot square, so it lacks the groundwork to build travel times, travel speeds, and related details into your campaign. For a rule of thumb, a horse carrying a rider but not weighed down can travel approximately 5 miles per hour (8 km/h), or 40 miles in a day. This is a great increment because it makes the Dragon Empire map distance from Axis to Horizon three days' ride. Only problem is that there are only those nice convenient Imperial highways between the primary cities, and everything else isn't going to be so easy.

Depending on how picky you feel like being, there are levels to which you can add to this, or you can just handwave it. My personal preference is to get a solid estimate on how fast my group is likely to travel on dirt roads or plains and just deal in increments of that amount. At the same time, however, it seems a bit weird to me to let a horse with a pretty beefy dragonspawn character with heavy armor, weapons, and kit move as fast as a horse with a petite lady spellcaster with no armor, just a bow and quiver, and minimal gear. (Perhaps it's too much dependence on mechanics in other games.)

I've decided that my PCs will have to travel gently and keep their weight down or risk going 3/4 speed and accruing the hampered condition for the horse. Hasn't affected movement yet, just ability to attack. Seems fair enough. If they try to push the horses faster, they'll tire sooner, so I've listed 1/2 speed and weakened for the horse if they travel longer than 8 hours a day at a gentle walk/trot pace, or galloping for more than a mile or two at a time.

Stats for horses also created by me, since there is no official listing for them.
