This stage takes a long ride up the Adriatic coast before tackling a tough finale. Starting in Castellalto, the route descends across the urban centre, all the way to the valley floor. The first 100 km are raced on wide and straight roads, mainly along the coast. Upon reaching Castelfidardo, the route takes a first pass through the Selva della Battaglia and then enters the closing circuit, to be covered 4 times. The circuit (approx. 23 km) is a succession of climbs and descents, with just one short flat stretch, roughly halfway. The first ‘wall’ (where KOM points will be awarded upon each pass) has gradients of around 18% over long stretches in the final part.
The final kilometres undulate continuously, with two-figure uphill gradients past San Rocchetto. The last kilometre across urban Castelfidardo is fairly complex, as the route rises steadily and markedly all the way to the home straight, on tarmac road.
