Taximan, I have recently discovered the joys of wind-assisted cycling. This was motivated partly by the need to fit my cycling in with family activites. What I do is nip out, lick a finger and stick it aloft, then either get Mrs Gti to drive me out and drop me upwind of home or ride downwind and agree to meet at the destination cafe. I have had enjoyable rides from Blackpool to home and from home to Settle, both at high speeds for little effort. We also have a route, which makes a circuit through a spooky marina called Skippool, the town of Clevelys and the prom up to Fleetwood and a crossing of the Wyre estuary by foot ferry. This is a great ride for my family because it's completely flat, there are plenty of cafes, you can do it clockwise or anti-clockwise and the wind blows you exhilaratingly fast right along the prom for several miles. There's the excitement of the ferry crossing and best of all, the thrill of working your way through the Clevelys DSS dossers, fish, chips and candy floss zone and suddenly emerging on the seafront where the vista of the sparkling sea and the bright sunshine just takes your breath away.
I'd have thought the same kind of rides would be possible with your location on the east coast.
