You can only run away from something for a scene at most. Beyond that it loses its impact. Anything longer than that, your characters need to be running towards something instead.
Away from is reactive, a response to something rather than a determined choice: There’s a monster behind us and we don’t want to be eaten! AIIIEEE! It’s chasing us!
Towards is active and implies planning and forethought from the characters: We need to get to the evac point before the chopper leaves, and then we’ll have gotten away from the monster for good!
I may refer to this in future as the GET TO DA CHOPPA! rule.
