Trying something new to track my aerobic fitness. 5K test loop, at any pace but constant heart rate. It was hard to keep the HR steady, and I was constantly having to make minor adjustments. Today was all walking, sometimes at a decent pace, other time briskly, and other times brisk with heavy arm movements.
