Can anyone recommend a jogging circuit in Barca? I'm thinking of runnning down Las Ramblas in the morning when it is not as busy.
Carretera de les Aigües (Funicular de Vallvidrera Station)
Carretera de les Aigües, 151B, 08017 Barcelona
This is one of my favourite running spots in Barcelona. Its not super central but in 20 you get there on the the train from plaça de Catalunya . The views are spectacular . I ran down las ramblas one morning a couple of years ago before doing 10k run. It was pretty surreal to jog down at 7am on a Sunday morning as no crowds.
I second Carretera de les Aigües, which is worth going to just for a walk, too.
Gran Via is also good for biking or jogging.
