TrailDuro Entraunes is a nature trail event held in the village of Entraunes, located in the Alpes-Maritimes department of Provence-Alpes-Côte d'Azur. It takes place in late July near Mercantour National Park, offering race options from short timed climbs to an 18 km trail race with 800 m of elevation gain. The primary distance falls within the Trail XS category, appearing concise but still demanding a significant mountain effort.
Rather than a single loop, the event features multiple timed sections: 5.2 km with 235 m ascent and 65 m descent, 3.2 km with 270 m ascent and no descent, a section of approximately 3.15 km descending 510 m, and a 2.2 km section with 175 m ascent. This structure provides an enduro-like character compared to a typical trail race, as participants navigate distinct uphill and downhill segments around a small alpine village. The location is adjacent to Mercantour terrain, emphasizing steep paths, mountain pacing, and managing frequent gradient shifts over the allure of large crowds.
