Terre des Dieux - Terra Di I 2026

Terre des Dieux - Terra Di I is a 165 km trail race based in Bastia in Haute-Corse, on the French island of Corsica. It is scheduled for mid-July and is part of the UTMB Index, listed under mountain, nature, and forest running. The main route climbs steeply through the Corsican mountains, with approximately 11,000 metres of elevation gain over the full distance. The 165 km trail is the most popular option, and the race organizers refer to it as “an immortal race.” This description suits the scale: it is a long mountain ultra for runners seeking Corsica at its roughest, not a road event with easy pacing.
