Oh nice. If I was still in London I might give cycling across it a go again. It's been a few years since I cycled from south-west London to the Docklands to do a datacentre visit. (Sadly it left me with too little remaining energy to actually work effectively, but anyway.) But now that I live in the middle of nowhere, cycling in London isn't really something I can do any more. (I could cycle in my local area, and my brother-in-law keeps hinting, heavily, that I should, but urgh. I don't know the area's cycle routes yet and I just don't feel like cycling these days. And mainly, I don't have anywhere I need to go that's actually a reasonable cycling distance from here.)
