The book records 20 routes based on over 20 years of mountain bike touring adventures in Scotland and Northern England. However we haven't just retired since its publication. Three "new" routes are in various states of development:
The Far Northwest is complete and presented here in the same format as the book.
A Yorkshire Coast to Coast (Almost) has been developed, ridden and written up in a text format here. It will be written up in the book's format in coming months.
A Lake District Circular is in development, but Covid and bodilly wear and tear have so far prevented riding or recceing. An outline map is presented to tantalise.
