I was half watching 'Doctors' BBC 1 a few days ago and I'm sure the running obsessed Dr told someone, as he puffed and panted into the surgery, that he'd run 2K. What?????? I really hope I didn't mis-hear this. I just love the thought of script writers thinking that 2K is enough to make a fit man huff and puff. I'd be much faster if I 'only' did 2K!
