The Trail de Serrabonne begins and concludes in Baillestavy, a small village in the Pyrénées-Orientales department of France's Occitanie region. This early-April event takes place in the Aspres massif, offering two mountain routes: the 31 km Santa Anna Trail and the 22 km Baillesta’Trail. Both are single-loop courses designed to be challenging, with the longer route ascending approximately 2000 m and the shorter one featuring about 1400 m of elevation gain.
The running takes place primarily on natural, forest, and mountain terrain, emphasizing climbing strength and trail handling over flat-speed performance. The Santa Anna Trail, the more frequented choice, can be completed solo or as a duo, broadening its appeal beyond a typical individual mountain race. Previous course details indicate a comparable long route of around 32 km with balanced ascents and descents, highlighting the steep and concentrated nature of the terrain surrounding Baillestavy.
