New route — first year running. Circular, 11.5km on dirt roads only (no trails, just a few village alleys at the finish). +200m elevation gain. Suitable for runners who enjoy mountain scenery without technical trail terrain. Starting and finishing at Vavdos primary school (alt. 753m). Route: From the school through the village alleys to Platanos, right onto the Karodromo — first ~920m shared with 6K and 21K, then the 12K continues on the forest road while the others turn onto the Eirini trail. ~1.5km with panoramic views of Kassandra and Sithonia. Loop around the Vigla summit (where the Prophet Elias chapel stands). One aid station at km 6.15 ('Liontaroudi' location): water, isotonic, nuts, bananas. Turning toward Agios Prodromos and Galatistra with gentle climbs, reaching the highest point of Vavdos village, then rejoining the 6K and 21K route for the descent through the alleys to the finish. Post-race: pasta meal by Melissa for all finishers.
