I feel like I am getting into a good routine of running every other day and doing circuit training every other day. My runs are not long (less than 6 miles total) but I run 4 miles at top aerobic effort. I am seeing steady improvement in my pace. The extra day of recovery really helps. I am down to 6:49 pace for 4 miles. I hope to be down to 6:20 pace by Christmas. When I get down to 6:30 pace, I am going to do a 4 mile test run at 7 minute pace to see where my heart rate is. I will periodically do this test and, it will also serve as an easier recovery day. My goal will be to see a lower heart rate at 7 minute pace over time. When I run hard for 4 miles my heart rate maxes out at 160bpm towards the end of the run. For most of the run my heart rate is in the mid-150s. My goal today is 6:45 pace.
