thanks, I tried both suggestions and all trains take over 6 hours via
Madrid. Maybe as i get closer to my trip other trains open up?
Just wait, Renfe are notorious for releasing their tickets in an unpredictable way. To quote the Man in Seat 61:
"Renfe is a law unto itself and loads what it likes when it likes, in blocks of dates. On major routes where it has competition, it may open sales up to 11 months ahead. On routes without competition sales may open as little as 30 days before departure, and often some trains appear before others. Did I say 30 days? I've seen Madrid-San Sebastian trains from 22 July onwards only open for booking on 7 July!
So if you go online and don't see the complete train service which you're expecting to see with over a month to go, WAIT, chances are that all trains are not yet loaded."
Eventually they will go on sale, the direct Euromed trains take you from Barcelona to Valencia in a bit under 3 hours.
