An interesting idea that doesn’t go the distance, “Marathon” attempts to parallel the personal and professional lives of a long-distance running coach prior to the Athens Olympics. Helmer-cowriter Antonis Kokkinos (“End of an Era”) fails to allow most of the characters to breathe as normal people, weakening the pic’s emotional content and ending up with a series of schematic relationships. Offshore chances look slim.
Driven coach Andreas (Yannis Kokiasmenos) is a man on the run — mostly from the various women in his life, all of whom see through his hard-ass front and treat him like an overgrown child. Sculptress Dimitra (Aimilia Valvi) wants to get married and have kids; bank employee Hristiana (Maria Zorba) cooks for him and knows he’ll always come back; vampish psychologist Elissavet (Stella Kazazi) uses him for sex; photog Martina (Sylvia Venizelea) is coolly professional. But his biggest challenge comes from the young, assured Myrto (Elena Tahiaou), the g.f. of one of his more promising runners, Petros (Mihalis Gousis). Perfs range from stiff to good (Kokiasmenos, Tahiaou, Zorba), but dialogue too often rings false. Tech package is so-so.
