unintented "speed work"

Wow - both Carol and I felt sluggish and tired until we realized that we were actually running pretty fast. We did 4.5 miles at a 10:51mpm pace. We had intended to do two laps (Liberty), but Carol wasn't feeling super, so we'll do that tomorrow or Friday. Overall, we're both glad that we ran, but looking forward to a morning run tomorrow. I don't like these afternoon runs as well.
