What a difference 25 degrees makes ....

The front came through yesterday. I'm really not ready for fall overall, but I sure wasn't ready for running in a heat index over 100 earlier this week, either (notice how I can't count syllables when my brain is cooked? ). Today I did 10.5 ... about 1:30/mile faster than the 11 the other day, at an average heart rate 21 bpm lower, on a slightly hillier route. Dang.
