In reply to Ciro:
An interesting suggestion which I can't see work for me... I miss climbing too much.
My plateau is a long but not a bare and arid one- I'm enjoying ticking at the grades I am operating at as there are many classics to be had.
It's more about aspirations that the plateau effect is felt.
Overall, my mojo is good however, contrary to the impression the OP gives. I was just wondering what others did.
All suggestions are good, and will be carefully considered ( I haven't ditched the couple of months off if I can find a substitute and can time it well).
