This proficiency allows a character to run long distances without tiring. Over the course of a day's movement, the proficient character can move twice their normal movement rate. If the character wants to keep it up for mulitple days, they must roll a proficiency check every day after the first, and on a failure, they cannot benefit from the proficiency for that day. If the character gets in a combat on a day spent running, they take a -1 penalty to attack rolls they make.
