A route added to the existing ones so that those who come for a four-day stay can enjoy an extra run on the trails of Doris. It is a timed race (not counted in the Stage Race standings) and can also be walked as a hike. It follows the old path villagers used to go down to the Mornos river and, once a year, to the chapel of Katagiannis (Kato Ai Giannis).
