Afternoon "Make-up" Run - L3-L4 Effort

Since I didn't get much running in this week, I jumped at the opportunity to run on Friday. I decided to make this a "hybrid" of the easy runs on Tue/Thu/Sat and the quality Wed run, because I expect to run long on Sun, and don't want to do too much prior to that run. Typical "hilly" run, as you can see from the heart rate graph at the left. Heart rate gradually rises to an average around 160 bpm with several peaks and valleys. By the end of the run, I was averaging about 164.
