In Letchworth the route divides, and you have a choice of going through the centre of Letchworth, or taking the rural route following the 'Garden City Greenway' around the east side. The 2 options are shown on the updated map available now to download or request a copy of the printed version.
A new section of path has been built from Letchworth Gate, Letchworth, around the north side of A1(M) junc 9 to allow easy access to south side of Baldock (A6141) or Graveley (B197) or Weston (Lannock Hill / Hitchin Rd).
There were a few instances of missing signs (or pointing wrong way!) mentioned in the guide - many of these have been addressed now, so it should be possible to ride without concentrating on the map!
Online guide is now available to the whole route with additional & useful information:
The Guide is divided into 3 sections, describing riding from North to South
