Desktop challenge!
Forget running. Forget time tables. This is map-oriented challenge.
What is the maximum number of different stations you can visit?
Provided:
* You can only visit (or pass through) each station once.
* You must change within LU stations (e.g. you can't change between Bank and Monument since these are different stations. The same goes for the two Hammersmiths etc).
* No non-LU routes allowed (such as rail, bus or DLR).
* Both start and end stations are counted.
Let's start by only submitting numbers (no routes) to this thread!
I have a route with 100+ stations...
Good luck!

Rather than working out a route, I figured I'd try and work out a theoretical maximum for the number of stations and gradually reduce it. To paraphrase Radiohead - you go forwards, I go backwards, somewhere we will meet...
There are 123 stations that aren't on a 'dead end', as shown on this map that I've hacked up (hello there, friendly LU lawyer!). The longest dead ends are Warwick Avenue to Harrow & Wealdstone (13 stations) and Leyton to Epping via Hainault (18 stations) so if you were to start at Harrow & Wealdstone, somehow do all 123 stations and emerge at Epping, that would give you a total of 154.
That's not to say that 154 is actually possible - you can't visit Ealing Broadway, Acton Town and North Ealing without either revisiting Ealing Common or finishing at one of those stations, for example. Will work at whittling down the maximum figure some more...

And I *think* I've reduced the theoretical maximum to 144 through a rather messy algorithm: if we make the optimistic assumptions that
- we're able to take the longest possible dead ends (H&W and Epping) as the start and end points
- we're able to visit all the interchanges
- at each interchange we're able to take the longest possible route to the next interchange
