Castiglione del Lago, Italy · Saturday 13 March 2027
Held in Castiglione del Lago in Umbria, the Strasimeno marathon takes place in the heart of Italy's countryside near Lake Trasimeno. The region is characterized by rolling hills, olive groves, and medieval villages that dot the landscape. The setting is peaceful and rural, far removed from urban marathons, offering runners the chance to experience the quieter side of central Italy while racing through a historically rich area known for its natural beauty and agricultural heritage. The course itself is a trail marathon that stays predominantly flat to gently rolling, making it accessible for most runners while still offering enough undulation to keep things interesting. You'll be running on dirt and trail surfaces rather than roads, which adds an element of technical footwork to the race. The elevation sits between 258 and 305 meters above sea level throughout, so there are no steep climbs to contend with, just consistent, subtle changes in gradient. Runners should come prepared for mixed terrain underfoot and expect a more natural, less controlled racing environment than typical road marathons. The trail setting means potentially softer impact on your legs but also requires attention to foot placement, particularly if conditions are wet.
