Courses which are multi-terrain are issued with a Statement of Measurement and are highlighted in grey below.
Calibration Courses which may used by course measurers are highlighted in green below
NOTE by the Measurement Secretary for Wales : This list of Certified Courses for this Welsh region includes all measurements from January 2000 to April 2007, and from April 2010 to date.
