1) I think that this is a cracking idea.
2) My only reservation is that it is 'only' the RRA record - the RTTC record is further (A Wilkinson 541)
3) I think that it is something that some official body should be encouraged to take ownership of (and ongoing maintenance, and my next point)
4) Four of the 5 most recent [RRA] 24-hour records were set on the LEJOG route. The last 3 of which are within 15 miles of each other. I think that it is a good story that all these happened in the same 'patch' and is something that a local council should celebrate (we have road signs 'round here saying that the London 2012 road race visited, for example). I like the idea of LEJOGers being able to cycle past (as an awful lot of them will, given that they happened on one of the most popularly used sections of the LEJOG) and going past the previous records on the way to seeing the current record - they can see the evolution (some of them will take half a day to travel the distance
between records - mind-blowing eh?). This also means that if the record is broken again (on the same route) that they can see the next one, the distance, the date etc. This does not have to be a one-off.
5) Let's not forget the ladies (although I think that the current women's RRA record was set elsewhere)
6) Quick, stick a surveyor's nail in before that paint disappears
7) I am glad it is not me that is going to have to use a trundle wheel to measure the distance accurately!
I also think that something should be done at JOG - a roll of honour with space to have new name added (I may have missed it in my haste to get going but don't recall a list of record times anywhere visible)
