Ran 15.1 miles @ 7:59/mile pace.
Weather: Upper 20s.
Got in a good workout today. It took a good while until I felt warmed up. The first five miles I felt stiff and my legs heavier than concrete. After that, I felt pretty good. Just pretty tired legs, which kept my pace down somewhat but still respectable for me. Splits were steady with little variation.
The cold and darkness were challenges, but that's to be expected in the winter. Thank goodness for headlamps. Good workout, and my third 15+ mile run in four days. Tomorrow I'm planning on 10 miles, and a rest day on Thursday.
