like hitchhiking to (insert interesting destination), and then asking for sponsorship. fuck off.
Running a marathon (or a series of marathons) is one thing because it actually requires training and I imagine running the thing might be pretty hard too.
Travelling accross Europe with Prague your final destination isn't hard at all. Just fun. That 28 hour stint I did at an airport after Benicassim 2008 was pretty hard...GIVE TO CHARITY YOU FUCKS.
