Riders who have chosen to do the Maratona course split off from the Middle course in the village of Cernadoi. The Maratona dles Dolomites proceeds from there to the village and uncategorised climb of the Colle Santa Lucia, after which the steepest of all climbs begins: the climb to Giau Pass. From Giau Pass the road goes down to Pocol, from where the course rises to the Falzarego Pass. There it reunites with the Middle course and having crossed Valparola Pass follows the same road through San Ćiascian and La Ila to the finish line in Corvara.
