Not much fog as I set off, but somewhat thicker as I went past Gatwick. A nice surprise to see Steph striding down the footway, looking good. Several motorists in unlit cars, which coupled with the fashion for grey paint didn't seem the best choice. (OTOH I did see them). Actually chatted with another cyclist as I went past the former Royal Earlswood Hospital on the cycle path, badly covered in chutney. He warned me that my pannier was about to fall off, but I explained it wasn't, it was an Altura laptop case and mounts on the piss to give heel clearance.
