Last commute of the year. And I got a p*nct*re!
Fortunately, I noticed it in my kitchen, so sat and swapped the tube (and dug out several flints & shards of glass) before setting out into the (relatively) cold.
Nice fast ride this morning with light motor traffic, but I only saw about a dozen cyclists in all
And my front brake finally objected to the abuse it's been getting without being cleaned. One side started dragging. I think there's some gunk in the spring. Bit scary over the big junctions (of which, of course, I added Waterloo, Westminster & Lambeth Bridge roundabouts, as well as St George's Circus, just for the hell of it), but manageable.
25km again. I'm hoping to get the same on the way home.
