Good post TheEd....However, i'm wondering why it is that you think running outdoors is more difficult to running indoors?
I see that all over the internet, with people suggesting to set your treadmill on a slight incline to compensate. However, there is never an explanation as to why. The best people do is casually mention wind resistance. However, its not so simple because walking vs jogging vs sprinting will result in differing levels of wind resistance which i believe is non-linear, not to mention possibly too small to matter at 'slower' speeds. (that is a casual/hand waiving statement of my own...hehe)
I found this article:

Which cites some research. The conclusion is that at middle distance speeds, there might be some effect...but at the speeds i'm looking at here (4:00/km...or 96s/400m) its going to be extremely minor.
They basically say that the energy difference and bio-mechanical differences to running outdoors are insignificant.
I haven't really seen any compelling arguments on the other front - to suggest treadmills are easier at my speeds...or even my speeds in another year of training.
Any thoughts?
