15 Miles on Sunday

I've been a slug this week. Due to a busy weekend, I had to move my saturday 15 miler to monday, and it was pretty tough. It's been hot out here lately, and monday, it was 85 when I finished my run. It was basically 7 1/2 miles uphill, (the last mile and a half I ran the brutal Runyan Canyon) and then 7 1/2 miles downhill. My legs got pretty beat up, especially my left calf. It's still pretty tenderoni. I'm guessing I have a muscle pull from the steep hill.
