I am really dragging today. I have been making changes to my diet, and eliminating sugar, so that is probably the reason. I got so hot in there on the treadmill that I thought I would drown in my own sweat. If it wasn't for the 30 below zero wind chill and no place to run, I think I would take it outside. But I'm calling today a "sort of " rest day. I did run 3 miles though. It feels great to get in some running every day.
