Dunno about amateurs, it's a pretty tough nationals course. They should get one national jersey at least (Eider Merino most likely), but for the men it's probably unlikely, I think Samitier and Carretero would be their biggest hopes, more likely Samitier. The circuit includes the
Alto de Baeza which is climbed five times. I think we're probably talking a ProConti rider. On the stage of the Ruta del Sol that included the climb the top Spaniards were Pello Bilbao, Ion Izagirre, Marc Soler and Rubén Fernández - would not be surprised if the latter takes this, having something to prove this year and will probably have the advantage of numbers on that Euskaltel team. Mikel Iturria and Jonathan Lastra are other possibilities, while on Burgos-BH there's always the possibility of Ángel Madrazo, who would actually be not unreasonably placed to win this you know... then there's those in Portugal like García de Mateos and Jesús del Pino.
The other thing is that a lot of the expats may have been prevented from travelling to race (other than Javier Sardá who of course won the HTV Cycling Cup) and therefore, shorn of their earnings in Japan, we might see people like Benjamí Prades and Marcos García strong... or even Paco!
