Treil Tredozio is a trail running event held in late March in Tredozio, a village in the Forlì-Cesena province of Emilia-Romagna. It features two race distances: the Lungo at 30 km and the Corto at 17 km. A 7 km Passeggiata is also available for walkers.
All three routes are single loops through mountain and forest terrain. The long race involves approximately 1,400 m of climbing, the short race about 600 m, and the walk about 300 m, ensuring uphill challenges even on the shorter options. GinPro organizes the event, catering to trail runners and walkers seeking a small community gathering over a road-race atmosphere.
