I would make a point of verbally expressing that you do not want to engage in anything verbally or physically--establish right up front that you wish to be left alone while still trying to evade or retreat. If the potential aggressor presses his pursuit--verbally and/or physically, you have at least established reasonable basis for intent for anything that follows after that. Guys have gone to jail for a very long time after a woman established that "no means no."
