Philadelphia, PA: Ran on the TM again this morning. Still felt sluggish. I am not sure why. It was really warm in the workout room so that could be a factor. Also, I think I found out today that the TM was not calibrated correctly. For the pace it said I was going it seemed really hard. I also noticed that the one next to me was going much slower even though we were supposed to be running the same pace. Anyway glad to get in the miles and the run but more glad that I will be heading home and looking forward to getting outside.
