Wow! Please tell me what the hell I am doing, cycling in over ridged and rutted ice and snow on a skinny track frame. Apart from having amazing fun, that is.
Didn't see a clear road until central Brixton and then didn't see another till Battersea Bridge. Every minor road was a juddering, bumping theme park ride; at one point, I found myself unclipping my left foot and cycling with my left leg stuck out, to keep balance (which is some trick on fixed). But there were so few cars on the road that, combined with good speed once I was over the bridge, that it only added 10 minutes to my commute.
Those drivers who did venture out were mostly very generous and considerate, for once. And it's the first time I've ever cycled to work with shouts of encouragement from pedestrians.
Did all this with bare knees, too, as my laundry rota got out of step and all my long tights are in the wash. Actually looking forward to the trip home.
