Are you tough? No, really, are you tough? Could you do this?
Well, could you?
Having run in sub-zero temperatures, I suspect that the suits needed to keep warm initially would at some point become excruciatingly uncomfortable and the focus of the run would become a concentration on temperature, with everything else forgotten.
Which might actually make the run bearable.
I'm all about allowing my mind to escape. Otherwise I might find myself weighted down by that daily marathon we all run.
How tough are you?
