I think that's the problem with long topics - vital bits of information can be overlooked.
Very nice to see Mice at HPC, even if she wasn't on a bike. I think we set off at the correct time, heading down towards Buckingham Palace. Constitution Hill was closed to vehicles but no-one seemed to object to us cycling along. When we got to Buckingham, it was just awash with people. As I was suitably attired in red, white & blue with matching flags (as shown in the photos), I think we may have attracted a bit of attention from the tourists.
Parliament Square was solid with traffic which we zoomed past although we couldn't turn left onto the Embankment, so we crossed the river to meet up with Stu at London Bridge, and User10571, further on.
I thought initially we seemed to be heading for Whitstable, until eventually we turned south towards Lewisham. Generally the roads were very quiet, and the suburbs slipped away, until we'd reached Brands Hatch. I think this was the start of the hilly bits! Somewhere around there, we passed an enormous mast, which in the gloom, with 3 rows of 2 sets of red navigation lights at the top, middle and towards the base, seemed to appear like sets of UFO's floating in the sky. Very eerie.
Out in the Kent countryside, with daylight around, once we'd got past Hawkhurst, the long bits appeared - long slow undulating uphills, followed by long undulating downhills. They really were a killer which wasn't helped by the fact that the speed limit around there seems to at least 80 mph. Rolling into Hastings on the A21, by some miracle, we managed to find an open cafe in the High Street which seemed a bit overwhelmed by a visitation of 15 cyclists, but eventually everyone was fed. They were very cheap there though.
Well done Adrian for organising this - I can see why Hastings is not likely to appear on the FNRttC official visiting rota though.
Once I've tidied up the entries, I'll post a link to the gpx route taken.
