Trail de Tende 2026

The Trail de Tende begins in Castérino, a village situated at 1,500 metres elevation above the Roya Valley, near Tende in the Alpes-Maritimes. This mountain trail-running event takes place in the Mercantour region, near the Franco-Italian border on the eastern edge of Provence-Alpes-Côte d’Azur. While event schedules often indicate mid-October, listings for Castérino also show early-summer races, meaning the precise timing can vary by race edition. The Castérino races are demanding and concentrated: La Giaure covers 16 km with 1,100 metres of ascent, and Le Tour du Mont Chajol is 32 km with approximately 2,400 metres of ascent. Other descriptions detail a larger program of four races, ranging from 13 km to 50 km, all featuring significant elevation gain. Tende Sport Nature 06 is the organizer, and the event is suited for runners seeking alpine terrain without the commitment of an ultra-distance race.
