There are three movement scales, as follows.
Modes of Movement: While moving at the different movement scales, creatures generally walk, hustle, or
run.
Hustle: A hustle is a jog at about 6 miles per hour for an unencumbered
human. A character moving his or her
speed twice in a single round, or moving that
speed in the same round that he or she performs a
standard action or another
move action is hustling when he or she moves.
Run (x
4): Moving four times
speed is a running pace for a character in light, medium, or no armor. It represents about 12 miles per hour for an unencumbered
human, or 8 miles per hour for a
human in chainmail.
