Saturday's Run on the American Tobacco Trail

I had a "long" run on the American Tobacco Trail on Saturday. It was a beautiful morning, clear with temps in the mid to high 50s. I wish my mojo had matched the great weather!  I felt sluggish, and was worried about my knee, so I ended up run/walking 3.81 miles in 1:08:31, barely breaking 18:00 for my average pace. Blah! Some runs are like that, though. I'm glad I got out there and got the mileage in.
