I am like a few of the previous posters and looking forward to the nice cool weather. I am from north Texas and I had to run at night when it was 95 with lots of humidity. Looks like it will be great weather Sunday.
I admit that I'm picky now that I live here. I live NW of DL up the coast and am used to summer mornings in the high 50s for running. But, I did three years at SMU in Dallas so I know what you are all experiencing. You will think it is perfect. Relatively dry and cool, but not cold.
