Aramón-Cerler is a Vuelta classic.
It was first introduced in the 1987 Vuelta, when Laudelino Cubino, a great underrated escalador in the classic Spanish tradition, was the first to win at the summit. It became an almost annual staple through the late 80s and early 90s as the Pyrenean counterpart to the more legendary Lagos de Covadonga, and also as a common transition from stages to Rassos de Peguera or the Andorran climbs (Andorra was really getting into hosting MTFs at its ski stations in the early 90s). Other winners there in this era included fellow traditional Spanish inconsistent climber José María Jiménez and Roberto Laiseka, GT winners like Delgado and Rominger (twice), Colombian escaladores like Fábio Parra, Oliverio Rincón and Martin Farfán, and the underrated Soviet climber Ivan Ivanov. It fell out of favour in the 2000s, especially once the owners of the resort, the Aramón Aragonese resort group (a joint venture of Ibercaja and the Aragonese regional government), started to funnel interest towards their southern resort, Valdelinares, in order to promote the Sistema Central as a holidaying and skiing area, where they held a much stronger base than in the Pyrenees where they had to compete with the French, Andorran, Catalan and Navarrese resorts. After one final ascent in 2007, won by Leonardo Piepoli after doing a deal (as ever) with eventual Vuelta winner Denis Menchov, the climb disappeared off the map; when the Aramón group got interested in hosting again a few years later, as well as Valdelinares, it was the Formigal resort they were keen to promote, so that got the Vuelta.
Similarly, the Aramón resorts used to rotate the important mountain stages of the Vuelta a Aragón, with Cerler hosting most recently in 2000, 2002 and 2003, all of which were also won by Leonardo Piepoli, so he can be considered the king of Cerler. Mikel Zarrabeitia, Lucho Herrera and Fernando Escartín have also been winners there.
Essentially this year it's the base of the whole race as obviously the first two stages are about jockeying for position but the mountaintop finish will settle everything. I'd expect Castrillo, Samitier and Barceló are the younger names targeting this, but the likes of Soler, Rosón, Javi Moreno, Duarte, Pardilla and Joaquim Silva may be among the main names to watch, while there's always the Spaniards jetting in from the overseas tours like Prades, Pujol and Mancebo to consider (and also Dan Whitehouse) because they always wreck the field in those Asia Tour mountain stages, but what that really means as against a European péloton is never truly clear. Alex Cano and 38-year-old Luis Felipe Laverde being in town is also interesting, but like the Portuguese péloton (which contributes a few decent names like Ezquerra and Nocentini) we're a way away from their season's peak so goodness only knows what their form will be like.
