CycloWorld recommendation

The Medio Fondo routes are ideal for riders who want to experience the legendary Col de la Loze without taking on the extreme 117 km Gran Fondo. You still benefit from closed mountain roads, excellent organisation and the unique high-mountain atmosphere — finishing on one of the most iconic summits in the Alps.
