Day 737 - 5k Run/Walk

I'm posting this a day late.  I went out for a run yesterday at lunch.  It was hot and humid and that took a bit if the starch out of me.  I got to about the 2.7 mile mark and decided to walk the rest of the way.  My heart rate was up and I was feeling tired, so I didn't want to over do it.  Could be that I need to hydrate more on days like that because I was sweating a lot during that run.
