+1 thanks for the map Ian.
Eck:
I wasn't meaning to be facetious - I didn't realise your ... unusual situation, sorry! I made that post partly because it had always puzzled me that this one course doesn't seem to be up on the web anywhere, either in route-sheet form or map. [IIRC all other TT "route sheets" are up somewhere, if you look long enough; I know where the West London ones are.]
