Anyone thruhike it yet?

It (mostly) gives access between the path and the sea too! Rules are here: https://www.gov.uk/guidance/manage-your-land-on-the-england-coast-path

This is pretty sick. Now we need a review of all the best pubs on the route.

Are there any good sites showing all such paths in the UK? Or just any recommend walks or hikes

Well, some of it anyway.
