Our original route past Chialvetta with the rough stuff section into Little Peru. A notable hike/push on footpaths in beautiful surroundings beyond Chialvetta rewards with some #bunkerresearch at the top and a dramatic unveiling of the altopiano from the Passo della Gardetta. If you rode the Col d’Izoard rather than the hike-a-bike option there and still want to earn your Rough Stuff Alps points on this route, then this is the route to take.

The route continues on a long descent to Demonte, a bike path road to Borgo San Dalmazzo and good resupplies at Limone Piemonte. It follows the same route as 4.2 after the Gardetta area, using a flat route between Demonte and Limone Piemonte.

Both 4.1 and 4.2 routes pass two bike shops around the 75km point, on the way out of Borgo San Dalmazo.
