The Railway Touring Club

Yeah, I rode part of the Transubayenne mtb route in the Ubaye valley on a road bike this summer, liked it a lot. I heard it was built once upon a time for a railway, but never finished. Nice gravel, mountain views, dark tunnels, small new bridges. Rough stuff on a roadbike, but ridable. There was water streaming on the ground for the whole width of the tunnel for a few hundred meters in one of them, but it's usually dry, I've heard.

Ciclovia Alpe-Adria Radweg/ Via Treviso / Fvg 1 or what ever you should call from Italy to Austria was interesting too. Smooth asphalt, old abandoned small buildings, villages, an old bridge made of steel. The tunnels have lights in them. Many of us used this in TCR last year.

There's a nice quiet one in Finland too, mosty gravel, from Hyvinkää to Karkkila .

Don't anything about the ones in UK though, but interesting thread.

Shocking assumption and clear failure to read the initial post, have you considered a careeer on track? :)

The railway parts of Avenue Verte are a lovely example of an old line converted very well, the small halt buildings being changed to toilets and water fountains are very handy and as a lot of it is on embankment, you get great views.

At night the rabbits and under tarmac tree routes cause a touch of concern though...,

but the French are great at converting disused railway lines to cycle routes.

That they are, the one in the vallespir were very decent despite the obvious shortcut made due to recent development.

Sadly the old metre gauge railways disappear after being converted from single lane to double lane road.
