Strava

Looks good, cheers - similar to other routes I've done before that haven't gone out that far, so it'd reduce the changes of getting massively lost while still close to london.

I've never actually used the Pilgrim's Way before - is it signposted? Or is it like a proper road, only singletrack?

Kent County Council have created a signed Pilgrims Way cycle route;

I'm going to ride (most of) it sometime in the next couple of weeks, will report back.
