It's Not the Heat it's the Humidity

I hate it when people say that...seriously. Annoys the living crap out of me but it's true. I've been struggling with the humid runs. Earlier this week when I did my 3 mile and 4 mile runs the temperature was in the low to mid 60's which is ideal as far as I am concerned. But today it was 75 which 78% humidity for my first step. It wasn't pretty but I finished. 32:52 for 3 miles. Next run is 5 miles on Saturday morning. Should be interesting.
