I'm home too - got in about half an hour ago.
The ride was far better than I expected (much more scenic in the non-audax sense of the word). It's definitely to be recommended. It was also really good putting faces to some of the names on here - and, as is to be expected, a great bunch of people to ride with.
I was a bit rushed at the start (some domestic stuff meant it was actually closer to 3 when I left, rather than the 2:30 I thought I was about to walk out of the door). A bit of Garmin shenanigins slowed me down around St Albans, so it was gone 8:30 when I got to the crossing, and 9:06 when I finally made it to the other side. I'd suggested to Adam and the others that they start and I'd catch up. Somehow I managed to shoot past them when they stopped for a convenience store break, so I then ended up waiting for them
I did spend the time usefully though, helping a nice young lady who was having trouble getting her tyre back on after replacing the tube. Unfortunately she wasn't going our way
But, other than a very noisy (horn honking) and vocal motorist who was upset that we'd stopped as 2 rows of 2 at some lights we were turning right at, where he was turning left (so wasn't hindered at all by us), it was a lovely, if a bit warm, day out.
I think I got it easier than the others, managing to run off the first 100 miles in the cool of the night, rather than starting out as the day was heating up.
Edit: forgot to say - many thanks to Adam for arranging the route!
