- wed: Lynnfield 3 mile route. Ran 3.0 miles. Really felt like I had no energy and no wind. This was an attempt at a HR training run, but it went badly. My HR was up 15 beats before I even started.
- thu: Lynnfield 3.63 out and back. Ran 3.6 miles. Another horrible run. My HR was up and I was extremely low energy. Suck.
- sat: Lynnfield 3 mile route. Ran 3.0 miles. Slightly better run today but HR was still elevated and I felt weak. I followed this with a 3 hour nap and I felt better. I must either have a bug, be suffering allergies or perhaps even recuperating from over doing it last weekend.
- sun: Lynnfield 9 mile out and back. Ran 9.1 miles for 102 minutes at 11:17 pace. After the horrible running week, this was a pleasant surprise. I kept my heart rate very low, around 138 for most of the run. I did not experience any of the symptoms that I had during the week, and I am forced to conclude that the problems I had all week long were due to overdoing it last weekend.
Anecdotally I believe that all the low heart rate training is paying off. Prior to starting this extended multi-month experiment I would have been running 13 and 14 minute miles to keep my heart rate in this range, especially for this distance.
