I ran nine miles yesterday morning at 7 am. It was already in the low 80s and the humidity was 100%. There was nothing easy about the run even though I fixed a bowl of oatmeal beforehand and had a lemon lime Gu 45 minutes into the run. I ran alone since none of my peeps showed up. There were plenty of other runners out there but it was a day to go alone and feel it. Maybe I would have done better with the distraction of a runmate.
My back was sore all day afterwards from the pounding. I think I need to go back to my Asics Gel Kuyanos. I wear them on my speed days and they feel great. My other Asics feel like clown shoes - big and clunky. I have a couple hundred more miles to go with them but I know I have to go back to the Kuyanos to get the cushioning.
