7 good miles today

I just returned from another good 7 mile run. My wakeup HR was 50, and I felt fine. There was a strong 15-20 mph headwind, but on my return trip the wind had mostly died down. This happens a lot -- wind in the morning and by 10 or 11 am it is on its way out. I need to get out earlier if I want the advantage of a tailwind :)
