Trail des Trois Secs is a small race day in La Ciotat, on the Mediterranean coast near Marseille. It pairs a 17 km trail run with 800 m of climbing and a 10 km walk, designed for runners seeking a challenging hilly effort and walkers wanting the same outdoor setting at a gentler pace. Entry numbers are limited to 300 bibs, which sold out quickly, with no waiting list spots available.
The trail route crosses the dry, rocky terrain surrounding La Ciotat, featuring natural arches and cliff sections that define the 17 km course. The event attracts local trail runners, outdoor walkers, and individuals drawn to a compact course that still offers significant elevation. Practical information, including rules, registered participants, and results, is managed via the KMS platform, which also lists separate walk and trail entries.
