The Adobe Sant Carles Trail uses two start points on Ibiza’s east side: the 12 km race starts at Cala Boix, and the 7 km race starts near es Pou d'es Lleó. These are short trail races in the parish of Sant Carles de Peralta, within Santa Eulària des Riu, held in November with late-morning starts.
Both courses conclude in Sant Carles de Peralta. This makes the event a point-to-point local trail run, not a loop starting and ending in the same place. Ibiza Blue Challenge organizes it, with assistance from Club Atletisme Santa Eulària, backing from Santa Eulària Town Hall and the Ibizan company Adobe. The race is now in its tenth edition or more.
