All the caches are placed a stones trow away from the National Route 1 Cycle way,
Tynemouth to Edinburgh Also known as the Coast & Castles South cycle route, National Route 1 hugs the coast between Tynemouth and Berwick-upon-Tweed via Blyth and Bedlington, heading inland to Edinburgh via Melrose. National Route 76 provides an alternative coastal option between Berwick-upon-Tweed and Edinburgh.
This one should not cause you too much trouble, though the gps can take time to settle down here.
I hope to keep adding to the route to make a series up between Blyth and Seaton Sluice
Well done to n901cag on FTF
