Most of the roads were almost entirely clear, excepting the very local roads near to my house, some of which are no-through, so see little traffic. On studded tyres none of that was too bad however.
The cycle paths were another matter. On one, there had been a significant amount of pedestrian traffic (a shared use path), but those footprints had then frozen, leaving a very interesting surface to cycle on! The worst bit was the Clapham Common cycle path. If you don't need to go that way, I'd avoid it. It had had more cycle traffic than most of the other bits of cycle route I'd used, and was more churned up in places, which made it fairly lethal. Looking at the tracks left, it looks like most of those users had been using narrow high pressure tyres, and had cut deep ruts, which have variously either formed hard lines which catch your tyre, or mashed the material up into a slushy, icy, slippery mess. It wasn't helped by some of them being seemingly incapable of cycling in a straight line, so their path weaved back and forth across the path.
If the weather hasn't caused it to depart by this evening, I'll be looking at another route home which avoids going across that common. Tooting Bec Common was a little slippery in places, but much easier than Clapham Common. I didn't actually come off on Clapham Common, but the wheels slid significantly on a lot of occasions, and I had one foot out and ready to put it on the ground because it got so unsteady.
I checked the temperatures before I left, and most stations were reporting around -1°C, and it felt quite mild. Thankfully there was virtually no wind, so it was quite easy going.
