We get at least 2 or 3 emails a year along these lines, informing us of mistakes in a checkpoint’s grid reference, in the handbook. We think this is mainly due to some of the grid references no longer being close to the checkpoint name on the map, this can occur for a number of reasons.
The event has been running for over 40 years so the original checkpoint locations and names were taken from imperial scaled maps. When the maps were rescaled to metric some of the place names were relocated.
The checkpoint location has had to be moved due to landowner requests or a better location being found. This occurs from time to time, since the new location tends to still be in the same general area it is felt that the name should stay the same.
Obviously changing checkpoint names is not a simple task, the tally artwork needs amending, all the paperwork needs changing and finally all the staff need re-educating (if you have been calling a checkpoint ‘fred’ for the last 30 or 40 years it’s hard to change overnight).
