I could get a 6-7am flight to Spain and be riding by say eleven am
Airports are usually on nasty roads, so do your research and you could have decent ride into a town of your choice, wolf whistling the spanish chicks. Be careful of the drivers, I once hired a car in spain and it was like star wars.
If you've prebooked a hotel, you can get there what time you want... you might get 150k in on the saturday. A meal in the evening will be more nutritious and cheaper than the harvesters we stop off in in this country after a ride. In the evening, go to a bar, and when the chicks know you're a cyclist they'll be all over you - in Spain they make cyclists into lords, believe it or not.
Next morning, if they've got a buffet breakfast, literally fill your boots with food. Get some cab numbers in case your bike breaks on the way back to the airport.
300k without having to worry about rain, for 150 quid. Should be done at least twice a year.
