Paul Valery once wrote something like: "Books have the same enemies as people: fire, humidity, animals, and their own content." I am thinking the same perils exist for runners.
No fire today and no animals that weren't aren't leashes. Our own content is always subject to inspection, introspection, and investigation. But this morning, the humidity was brutal. The air was 100% saturated with water. You know when you get out of the car and your glasses fog over -- that is not a good thing.
I ran with Christy and Machelle. We did a three mile warm-up followed by: 3 x 2 miles at marathon pace (6 minutes and 20 seconds per mile) with a half mile jog between reps. Our times were: 12:38, 12:39, and 12:36. We did a mile cool-down.
So here's the deal... Some things in life we can't change. We can either let those things distract us or deflate us or defeat us. Or we can just do our best and play with the hand that is dealt to us.
