Of course, this depends on what damage there is to the tunnel at Russell Square but IF the Piccadilly line is running at the time then I personally think that world record attempts should be discouraged.
There are two reason why I'm personally against such a thing happening.
First, it will involve people running through stations. If there are still lots of police about at certain stations then it's going to excite suspicion.
Secondly, it will be disheartening for those of us doing this for charity if some muppets decide to try for a world record when that is NOT the idea of this day.
And it has nothing to do with Geoff and myself worried that you'll take our world record - you've had over a year and you still can't do it

I think most people will be in agreement with what I've said here if the whole network finds itself up and running at the time of the event.
