Trail Sierra de Partara

The Trail Sierra de Partara returns to Aínsa, capital of the Sobrarbe comarca (Huesca), on Saturday 6 March 2027. The race runs along the paths of the Sierra de Partara, the terrain that rises alongside the medieval town, and sets out to discover the most emblematic corners of Aínsa and its Pre-Pyrenean surroundings in a late-winter mountain race. It offers two distances for different levels. The long one, 24 kilometres and 1,100 metres of elevation gain, demands good preparation to string together climbs and descents along the sierra. The short one, 14 kilometres and 550 metres of elevation gain, is a more accessible option for those starting out in trail running or looking for a demanding but brief late-winter race.
