Agree about Madrid, bob. We were there two nights in April and absolutely loved the city. Valencia remains my favourite of Barcelona/ Madrid/ Valencia though.
Did my second track session today, 200m fast, 100m recovery, phew it's tough this speed work stuff!
In Valencia we have stayed twice in apartments in the old town, there are some amazing deals and you get to stay in some amazing quirky old properties if that is your thing, although lack of a lift on post race Monday is entertaining!
tmbrntt, personally I cannot sing the praises highly enough of the old town area. More bars and eating places than you could ever do justice to all with a fantastic Spanish vibe. Each year i have setoff from our accommodation on Sunday towards the start and ended sharing a taxi with other runners.
