Trail del Cinghiale is a late-autumn trail running series on the paths around Palazzuolo sul Senio, a town in the Province of Florence in Tuscany. Runners can choose from short trail distances to a full mountain ultra, with races listed at 13 km, 20 km, 35 km, 45 km, 60 km, and 100 km. The longest options involve significant climbing: the 45 km route has about 2,610 m of ascent, the 60 km about 3,560 m, and the 100 km roughly 5,700 m or more depending on the listing.
The routes use mountain, forest, and nature trails rather than road sections, and the 100 km race is listed as one large loop. The 35 km race is marked as the most popular distance, while both the 60 km and 100 km races have drawn more than 100 runners in a recent edition. Weather is part of the identity here: runners are told to prepare for snow, rain, mud, or a clear sunny day, which fits a race held around the turn from October into November.
