In reply to althesin:
I did a similar exercise about 5 years ago and am probably the last person to have done the routes at Whitwick as they are now landscaped into back gardens for the houses on the site of the old garage.
I don't know if a Leicestershire guide will ever materialise as it will be too fraught with access issues and cover too much indifferent rock to be viable.
There may be some merit in a midlands guide covering all the bits from Shropshire, Leics etc
