15 turned up in the end. Mywindsock said temp was 30.5C, which sounds about right (started at 18:45).
Pace was high. Nobody obviously suffering in (or complaining about) the heat.
I was actually very pleased with my performance. 8 in our group ( I go in Group 2 these days). Dropped 3 of them by halfway. Dropped another 3 up the final shortish hill with a couple of miles to go - managed to stay on the tail of the fastest guy (one of the club racers). I Refused to come through for a pull

for a while, then foolishly tried to drop him on the final short bump before the finish. He stayed on my wheel and I had nothing left for the run to the line.
Great fun though - loved it.
