The key climbs

Puerto de Aín, km 37 to 43. 5.8 km at an average of about 4%, from 350 m to 580 m. The road climbs gently for most of the first 37 km as the course heads inland, so you reach the foot of the climb already about 350 m above the sea.

Salto del Caballo, km 78 to 87. 8.8 km at an average of about 5%, from 320 m to 780 m, with its steepest kilometre at around 8%. It is the longest and steepest climb of the day. The second feed station is at its foot, at km 77.

Technical sections

The descent from the Salto del Caballo includes a series of hairpins at around km 91, and there are tight bends through a town at around km 101. After the last feed at km 117 the course is mostly downhill back to the coast, with a short rise at around km 133, a stretch of rough road at around km 146 and urban roads for the final kilometres into Castellón.
