Three Municipalities Half Marathon
The queen of winter races between Civita Castellana, Nepi, and Castel Sant'Elia
About Three Municipalities Half Marathon
The queen of winter races in Tuscia
The Three Municipalities Half Marathon is one of the most beloved and long-standing road races in Lazio. Every year, on the last Sunday of January, it draws thousands of runners to the Agro Falisco, the area of the Viterbo Tuscia surrounding Civita Castellana, in the province of Viterbo. With its classic distance of 22.4 km and a route connecting three towns, it has earned the nickname the queen of winter races: an event that effectively kicks off the regional running season and, despite the January chill, never fails to thrill.
A loop connecting three towns
The feature that makes this half marathon unique is its inter-municipal track, which links Civita Castellana, Nepi, and Castel Sant'Elia. The start and finish line rotates between the three towns each year, allowing each community to take turns hosting the event. The route crosses the Faliscan countryside, skirts ancient aqueducts, the Ponte di Braccio bridge over the Treia creek, and the tuff gorges typical of this corner of Lazio, before climbing back toward the historic centers. In the final stretch, competitors parade through the heart of Civita Castellana, the city of the Cosmati, passing through the main square and the Cathedral before crossing the finish line.
A history spanning over forty years
Started in 1980, the Three Municipalities Half Marathon reached the milestone of its 46th edition in 2026. It is organized by A.S.D. Atletica Nepi, a historic local association that has made this race its signature event. Over the decades, the race has grown to regularly exceed two thousand participants, becoming a benchmark for runners throughout central Italy and for sports clubs in Lazio.
Sport, territory, and community
Much more than a simple competition, the Three Municipalities Half Marathon is a collective celebration involving the entire Agro Falisco. Along the route, the towns come alive with the cheers of residents, refreshment stations, and the participation of local administrations. The race showcases the historical and landscape heritage of Tuscia—from ancient water systems to medieval fortresses, from tuff gorges to villages—offering participants a different, athletic way to discover this territory.
