Some dry heaving while running

Holy cow, it was HUMID this morning.  Around 85%.  I did some coughing during the first 10 minutes of my seven mile run and it felt more like dry heaving than coughing.  Felt like I could barely move for the whole time, and my mile splits proved it!  My big body just doesn’t like running in the heat and humidity.  I tried a different shoe lacing method to try to help keep my ankle from rolling around as much. I guess my legs didn’t feel as bad during the run, but my calf muscles feel a little tight now.  Oh well.
