Well, I did it. Today was better. I only gave myself 1/2 lap (4 laps a mile) to warm up. I slow jogged almost 1/2 of it. When I walked I walked at 15:00 pace. I kept pushing my heart rate to 165 - my so called Maximal Heart Rate. Just so you know I was only walking a pace of 20:00 when I started training for my last 1/2 marathon.
If I could just get over the mental stepping on the treadmill.
