Medieval Trail is a trail race of approximately 20 km held in Mussomeli, a medieval hill town in the province of Caltanissetta, central Sicily. It typically occurs in early September and holds a UTMB Index label. Recent editions have been around 20 to 22 km with close to 920-960 m of elevation gain. The event's slogan, “À l’assaut de Mussomeli!”, reflects the course: this is a short but steep Sicilian trail race, not a flat road run.
The course crosses trails within preserved natural areas surrounding Mussomeli. The medieval town provides the race's name and backdrop. Past results indicate a modest participation, with one recorded edition showing 54 finishers, suggesting a local trail gathering rather than a large international event. The organizers aim the race at trail runners seeking a challenging shared effort, featuring one primary distance and a welcoming atmosphere where runners test their limits together.
