Done. Well, at least, I'm claiming it, purists may object.
I set off into the snow, and it really wasn't bad. The road surfaces were good, the snow was dry and it wasn't too cold. My plan was to aimlessly loop round the suburbs, so I could always get to a station if the weather got really bad. I realised I'd forgotten my phone, so I looped back home to pick it up at the 25k point. That alone would be enough to disqualify me from the imperial century a month challenge, but worse was to come. After 40k or so I thought I'd see what things were like outside the conurbation, so I rode up to the North Downs ridge at Titsey. Bad move.
As I rode the snow changed from fluffy flakes to little icy crystals, the temperature dropped and the wind picked up. I stopped for a snack and a swig from my (frozen) water bottle and headed back from the ridge, right into the wind. I had to pedal downhill at times. Then things started to go wrong with my bike: gears, rear brake and front mech all started playing up. This turned out to be due to a thick accumulation of ice on all of the bottom of the bike - and on my boots! The descent from Titsey to Bromley via Biggin Hill is normally a fast one, but this was hard work. There was ice all over the bike , and my feet and hands were frozen.
I popped into the station at Bromley South for a hot drink. 77k done. Once I'd thawed my numb hands I phoned my wife and by a bizarre coincidence she was standing a few metres away, having popped out to do some shopping. We took the train home together, and the ice from my bike melted into a huge puddle on the train floor. At home I thawed my feet and hands, put on some dry socks, and then set out for a final 25k loop which I completed without incident.
102k done. Two visits to home. A train section, and a change of socks. I'm still claiming it
