I don't know if this has been done before, but I'm basically interested in something of a mini Tube Challenge marathon, involving doing lots of the minor challenges in one day. It would normally involve Zone 1, The Bottle and All-Lines, but we can substitute All-Lines for DLR while the Waterloo & City line is closed. Besides, how many of you have done that challenge before?
The programme would be something along the lines of:
1030 Meet up at Oxford Street
1100 Bottle Challenge (with or without those stations)
1400 Meet up at Shadwell for a quick lunch
1500 DLR Challenge
1800 Meet up at Shadwell again
1830 Zone 1 Challenge
2200 Meet up at the usual pub for results
We could draw the starting stations in advance, but then we lose the 'excitement' of frantic route-planning after the draw. Yes, half an hour may not be a lot of time, but if we had the usual hour for each challenge we'd be getting to the pub around midnight with no way of getting home. You'll just have to think quick

We could start earlier to allow more room for error, but that would force most people to use peak tickets.
So what do you think? I'll put a poll in this thread to get a good representation.
Oh, by the way, the reason I want to get a lot of Tube Challenging done before I start work is because my new employer probably won't like me doing it. Yes, I have applied for a job with a certain London Underground Limited...
