Hi All

Looking to purchase a guide book for the Peak District with circular walks in the 10-20 mile range, including all grades of difficulty.

Done quite a few circular walks on the southern part of the penine way but looking for other stuff to do.

Thanks 

There's some routes you can grab on here by switching to UKHillwalking. Click on the 'route cards'  tab and zoom into the map to pick up some ideas.

...Here in fact. There's loads of Peak routes: https://www.ukhillwalking.com/logbook/r/find.php

This is a bit of a second hand recommendation as I don't have the books myself but quite a few people I know on Twitter swear by Paul Besley's guides, including many who are already seasoned walkers in the area:

I do have one of Chris Goddard's books but they might not be what you are looking for. They have some suggested routes but I bought mine more for his beautiful hand drawn maps and illustrations. It also contains a lot of interesting information. You can see inside the books on his website to get an idea of how they differ from a regular walking guide book. This is the one I have:

Some good circular walks in these books, The Dark Peak Challenges and the Saddleworth Discovery Walks  https://saddleworthdiscoverywalks.co.uk/the-guide/
