I would add in the weather to this list.
My best runs are in the dead of summer, 90 degrees plus with a suana suit for good measure. I feel so loose and flexible, and feel like I could go all day.
In cold, rainy/snowy, windy conditions, my joints feel like they're covered with rust, and the cold air makes my lungs give out quicker. For some reason, my lungs cannot handle training in cold (sub-30 degree) weather.
