I had to go to Putney to pick something up. Cheap excuse to put in a few more miles. To avoid hills, I went through Wandsworth.
Biiiiiiiiiiig mistake. Huge. The South Circular is closed, and I had to battle my way along Putney Bridge Road, getting stuck behind lorries jammed in the gridlock and the like. Many riders had given up, and were riding on the pavement. It was tempting, but I don't really do that. And I don't know the backstreets well enough.
Once I was up Putney High Street, it was a breeze. Then, coming back through, I hacked half of the High Street, then went off onto the cycle route and over Wandsworth Bridge (what a crap bit of farcility that has!). Surviving the right turn, I got moving again along to the Embankment, and went to Lambeth Bridge again. Not a nice filter to a right turn there.
The last bit of crappy design is at St george's Circus, where there is a bike lane cut through, but it spews you out amidships of a bus stuck at the light, and does its very best to send you down Westminster Bridge Road, which is pretty much the way you came. If you want to go along Borough Road (and, having done it two days running, I observe that every cyclist going through there did), you have to get a bit creative with the use of the junction and the interpretation of traffic lights. V.dangerous, and I Do Not Approve.
