I love their "Press Conference" video where Marc explains the months of planning, "lots of Microsoft Excel and playing around with maps". In the video he tries to make the challenge look as "sexy" as possible, which is some mean feat. He said: "Ironically in order to make the journey fast, I had to avoid using Tube trains and a lot of commuters would agree with that strategy."
The end is a classic. When asked why he did this, with true Mancunian wit, Marc said "It was either this or try to get 40 mates into a a mini. You've seen the video and I'd probably struggle to find 40 mates to be honest".
"The magic, mystery & sometimes maddening shortcomings of London's Tube are documented with love, enthusiasm & sometimes despair by its unofficial social historian." The Guardian
