When I left on my run, it was 73 degrees, but I didn't account for the near 100% humidity.

The air was so thick you could cut a slice and store it later. I covered about 4 and a half miles, then went to the gym for another 40 minutes on the elliptical to make certain I was keeping up with my training load.

I was unprepared for how hard the steamy day hit me, by the time I got finished with the run it was 81 and like running in a dryer vent.

Still, I saw it through!
