Would you ever try the London Tube Challenge?

Hm, I think I'd try that in Vienna (which would take only a few hours). Is it allowed to take a regional train as a shortcut from one subway-terminal to another one?

We actually had a similar thing during a scavenger hunt. We had to stamp a fake ticket (of course we had a real one too ) in each one of Vienna's tram lines. That's what it looked like.


Hmm, I think, I'll figure out a route and try a tube challenge here.
EDIT: It should take from 9:12 to 12:50, which would be 3 hours and 38 minutes for 65,6km of subway and a few km with trains and a tram.
