I am riding the coast from Mojacar Playa to Villa Rico's with a loop up past Vera town. If you love a hill or two this area is a great place to train, if like me you like distance without too many hills you will love it here too! Roads are in good condition with some excellent cycle path provision in busier areas! 3 months sounds great, good luck and I hope you love it!
+Andrew Thompson the tcx has been a dream since I bought it, very comfy riding position for me which was important. Sits up well on the roads and was unstoppable in the recent snow and boggy weather in the UK winter. Obviously it isn't a pure roady so the gearing isn't made for too much climbing (neither am I) all in all I am really happy with my choice, a spare set of slicker tires for the summer and I can't see me parting with it any time soon!
