ROADBOOK
Roadbook S1 Borin — the route section by section
4 km from PortoPiccolo between the trenches of the Karst front, Sistiana and the Costa dei Barbari: every section in the order you meet it.
The S1 Borin starts from the Bora Village in PortoPiccolo and returns there after 4 km: it is the shortest loop of La Corsa della Bora, a non-competitive route with no final ranking. This page describes the course in the order in which you meet it, section by section.
The beach of PortoPiccolo and the trenches of the Karst front
The start is on the beach of the Bora Village in PortoPiccolo, with the sea behind you. The first section climbs among the Great War trenches of the Karst front: white stone, Mediterranean scrub and wild sage, on a well-marked trail with a steady gradient — no sudden ramps, suitable for anyone tackling the Karst for the first time or walking with a child.
Sistiana/Sesljan — what changes in 2027
Until the previous edition, Sistiana was a junction: the longer distances carried on inland, while the Borin turned straight back towards the sea. In 2027 this changes — Borin runners are the only ones, of all the races of La Corsa della Bora, to reach Sistiana and carry on from there towards the coast instead of turning back at once: a stretch of Karst crossed on your own, with no other competitors around, that no other distance of the event covers.
The descent to the Costa dei Barbari
From Sistiana the course drops towards the Costa dei Barbari, a wild stretch of Karst coastline between Sistiana and PortoPiccolo, with no beach clubs, hidden coves and an open view over the Gulf of Trieste. The ground is Karst — live terrain, the odd root, watch where you put your feet — and the descent, short as it is, is steep: it is the hardest point of the whole route, despite the minimal distance.
For children it is a section suited to those who already have some familiarity with trails, not an absolute first step. The only real thing to watch is technical, not a matter of pace: here you need trail shoes with good grip, whatever speed you take the descent at.
The return and the finish at PortoPiccolo
From the shore the trail returns to the beach of PortoPiccolo, where the Borin reaches the same finish as the other distances of the day: same beach, same celebration. Anyone who has run the Borin takes home a stretch of coast — Sistiana and the Costa dei Barbari one after the other — that no other competitor of La Corsa della Bora covers in the same way this year. Four kilometres, but well chosen.
