I cycled in too - 9 miles into the City.
Was surprised that there were not many cars/lorries/vans etc on the road. Perhaps some lucky ones have a bit of an extended holiday. But then there were quite a lot of cyclists out there. Surprising. Even more surprising were the true nutters out there in snow & ice-free London. They fall into two camps:
(1) those cycling with bare legs and those without a hat or some other garment to keep their heads warm.
(2) those who leave the bike locked up and commute by tube on a glorious day like this.
I took it easy on this first day in after two weeks' holiday and non-cycling. Stayed comfy and warm with, for added warmth, a balaclava, thermal long johns, overshoes, knee warmers, plus my combo of liner & winter gloves. I thoroughly enjoyed the ride, and was actually wondering what the reason was for the large number of cyclists out there today. New Year's resolutions for healthy & active living including weight loss, cycling to cut down public transport spending, or just a realisation that it was going to be a beautiful day?
