The Trail Monte Artemisio is a trail race held in Lariano, within the Parco Regionale dei Castelli Romani, offering two distances through chestnut and oak woods. The Short Trail covers 11 km with 350 m of elevation gain, designed for quicker running and for those new to trail racing. The Medium Trail is 20 km with 830 m of climbing, featuring more technical terrain and a more demanding profile.
The longer course crosses the Forre dell'Artemisio, a small canyon on Monte Artemisio, before ascending along the Artemisio ridge. This provides the Medium Trail with a more pronounced mountain character compared to the shorter option, while both races remain within the Castelli Romani landscape. This event marks its second edition, organized by ASD Città Castelli Romani in conjunction with UISP Latina, and is part of both the Circuito dei Castelli Romani and the Grande Slam UISP Natalino Nocera.
