It's great to have these time targets! It keeps you motivated right through your training and into the race itself. The reviews say this one is fast and flat so if the weather is kind those of you on the cusp of significant time barriers have every chance of hitting a pb which makes the post race celebrations all the more joyous.
I've booked in the old part of Valencia too. Having recovered from Boston I am beginning to focus on Valencia now, well once holidays are out of the way. Starting to try and rebuild my aerobic base so I am in good shape for November. Hoping to help a running mate of mine go sub 3 for the first time. We'll certainly be up for post race beers once a venue is decided nearer the time.
