The toughest time for me is sunrise. The 30 minute or so transition time for night to day is the hardest time for me.
That's why I try to pace the run so there's always enough time for a nap or a break from fog and other icky conditions. Our natural clocks just don't want to be awake between three and four a.m. I find a 30-45min nap to be the best and only thing to fix that. Sometimes, if I've been running the same shift, I can make it to just before sunrise -especially out west- before needing to stop, but often a jaunt around the truck and some stretching will do the job!
