My runs happen at 6am these days. Tonight my workout didn't start till 7pm. (biking). Its dawn or dusk that I run. Thankfully we have well lit areas that I can run. In the winter, I run in the dark too because of early sunsets.And as ennay said - finding that sweetspot for the slow run. I find that outdoors my slow can be 4.7 - but after too long my quads start to ache because I'm doing more of a lunge jog in order to slow to that pace - but I can regulate breathing and then can start going faster again. Having the GPS/HRM to go by is a nice techie gadget that I can see what i'm doing after the fact. I can make sense of my workouts.
