What Was I Thinking?

My schedule got a little mixed up this week.  I'm battling a hip/leg injury that has my running on hold but after a week of rest, I wanted to test the waters.  So I had a short 4 mile run planned for today.  I was supposed to go out at 6 am before the heat kicked in but justified sleep over the wake up call.  Family plans had me busy until 2 pm and a major thunderstorm was scheduled for 4 pm so my running window was very small.  With 90+ degrees and almost as much humidity, I attempted my run.  Have you ever had the experience that you feel as if you just might boil to death?  I mean your insides, your blood and all other bodily fluids coming to a full boil?  Well, that's how it felt.  I wound up running for about 3 1/2 miles and walked the last 1/2.  It took a full hour to bring my core temperature down.  And unfortunately, I am only a smidge better with the rest.  This too shall pass.  But really, what was I thinking?
