Oh yeah - runner here.
I'm lazy right now though, not training for anything, so my limit for casual running is about +10
But if I needed a 12-miler, I'll take -1 deg over a treadmill ANY day!
I have a really good treadmill that I got for my daughter when she ran h/s CC & track, but running on that thing for me is mental torture!
