Nestled in the Stelvio National Park, the Marathon route is the most challenging of the Alta Valtellina Bike Marathon. It runs mostly on compact dirt roads, with sections of varying difficulty and breathtaking views. After passing through some of the most beautiful valleys in the area, such as Val Fraele, with the Cancano lakes, Val Alpisella, Val Vezzola and Val Verva, it reaches Forte Venini in Oga before returning, downhill, to the starting point in Rasin.
