It's just a little pill (that I consistently forget to take)

I'm worn out, and I think that I know the reason. I've not been taking my iron. I can blame the weather, after all it was 80* today at 8am. That takes a lot out of a person. But, I know that my tiredness is more than that. Dammit. I can't stand it when I don't take care of myself. Today's run, 4.5 miles, should have been easy one, but it wasn't. It felt long and tiring and blah. I did push the pace a bit, but not that much. I did run the wood chip path for half of the park, but not the whole park. I just feel like this should have been a better run. Stats: 4.5 miles in 45:56 for a 10:13mpm pace
