Hi Richard,
Just completed a North Wales Circuit comprising bits of Border Raid, North Wales Cycleway, Lon Las Cymru and Lon Cambria. Have linked the write up to your main Border Raid description (but is there an option to link the write up to the other routes we used as well?).
Ps. Northern part of Border Route (Welshpool to Rhyl), fantastic! Well done. Deserves to be an official route.
