The RunLondon site now has guides for the actual races available. Reading the Hyde Park one, I note that there are neither changing facilities nor baggage facilities. I think there will be a lot of miserable people around. Particularly if it's cold or raining. I seem to remember that last year there were lots of shirts etc discarded on the bushes near the start, despite the warnings about how clothing left at the start will be collected up and disposed of... Maybe if it's cold they'll hand out space blankets. What's the stock symbol for Bacofoil?

The Piccadilly line will be closed between Hyde Park Corner and Acton Town on that Sunday. Well, that just adds to the fun, doesn't it? (Although I suspect that's just a continuation of the ongoing Sunday engineering works they've been doing recently).
