The Roma–Ostia Half Marathon is Italy’s most prestigious and best-attended half marathon, drawing thousands of runners each March to a course that links the Eternal City to the Tyrrhenian Sea. Starting in Rome’s modern EUR district, the point-to-point route flows southeast toward the coast, finishing near the beachside town of Ostia. Known for its fast profile, occasionally aided by net downhill and favorable tailwinds, it’s a popular stage for personal bests and elite performances. The event features three race formats: an elite field, an open amateur race, and a “Business Run” that doubles as the Italian Corporate Half Marathon Championships. Organized by Gruppo Sportivo Bancari Romani and RCS Sports & Events, the Roma–Ostia race delivers a world-class running experience along with the warm, spirited support of Roman spectators.
