Col du Sommeiller (long)

Piedmont • Italy • Start/finish: Bardonecchia • Distance: 140 miles • Riding time: 7 hours • If the basic route up Col du Sommeiller doesn't sound tough enough, this longer version swaps Col Basset for a longer run on the unpaved Colle delle Finestre and the Assietta. This is not a route for the faint-hearted, the inexperienced or the unprepared. Not suitable for street bikes: only adventure bikes
