The construction ἀπολίσθοι τρέχοντος employs the present participle with the aorist optative in a periphrastic sense, where the participle τρέχοντος (genitive absolute or genitive of the object of the verb of fearing/avoiding) indicates the simultaneous action. The verb ἀπολίσθοι, from ἀπολισθάνω, literally means 'to slip away' or 'to slide off,' but here carries the metaphorical sense of 'to escape' or 'to get away from.' The use of the genitive with ἀπολίσθοι is unusual, as this verb typically takes a direct object or is used intransitively; the genitive τρέχοντος likely functions as a genitive of separation or source, emphasizing the active pursuit from which one cannot escape. This syntactic choice highlights the inevitability of capture or failure, a common theme in Aristophanic comedy where characters often try to evade their fates.
