I ran 4 miles again

I ran my four-mile route on the Jordan River Parkway again today. I wasn't as energetic as I was yesterday, and I ran slower, 11:30 to 12:00 paces. I was out an hour earlier, and it wasn't quite as hot as yesterday during my run. I noticed it was 92 (F) in the shade about half an hour after I had finished my run. If I still feel tired tomorrow, I'll take the day off; otherwise I'll run the four miles again.
