Running

Characters may choose to run; a running character is not normally allowed to attack (but see Charging, below). Running characters can move at double their normal encounter movement rate. Characters are allowed to run a number of rounds equal to 2 times the character's Constitution, after which they are exhausted and may only walk (at the normal encounter rate). For monsters not having a given Constitution, allow the monster to run for 24 rounds. Exhausted characters or creatures must rest for at least a turn before running again.
