In reply to BnB:
> Yes fitness aims are a spur for me as carrying loads uphill (ie winter and multipitch climbing) is my only strength-building activity at the moment. Fortunately I live in Hebden Bridge so I can mtb out the back door.A few local friends swear by their road biking, completing the TdY sportif yesterday. I doubt you'll see me in Lycra however.
Mountain biking is the gateway drug, it's only a matter of time before you try a road bike
I too used to treat it as a wet weather alternative to climbing, but then I discovered that it was even more fun in dry conditions. And rather than losing weight, I've developed these nice bulky legs, which are a right pain on anything overhanging.
And Hebden bridge - so much good riding on your doorstep - you may as well sell your climbing gear now.
Apart from anything else you'll need the money for maintenance of the full-suss, and deposit for the road bike
