An excellent video exploring the un-glamorous but common accounts of routes in hoplite warfare conducted by a team of French military historians and 400 passionate reenactors. Note: the experiment is scripted for a segment of one side to flee at varying distances from the point of contact, with the rest of their formation then choosing how best to preserve their "lives", in order to see how the dynamics of the flight and pursuit turn out. The video is in french with english subtitles available, but if you don't want to read you can skip to the actual reeenactment bits about a third of the way in.
