Day 58: 5mi, 42:27

Back on the treadmill today. About 3/4 of a mile in, pain flared up in my right calf/Achilles area again. I almost jumped off, but instead slowed and changed my gait. I don't know whether this is what I should do (probably not), but I kept running anyway. The pain subsided but didn't go away, and started to rise again at about 3.25 miles. I think this is related to the injury to my right knee a few weeks ago, which has also been generating persistent pain. And on top of this, I've got a mild chest cold. I think that's all my excuses for today.

The good news is that my times seem to be coming down for the 137 max HR. Today's 42:27 compares to the 42:45 on Day 51, 44:49 on Day 42, and 44:00 on day 32, my first day of low HR training. I don't count the 41:49 on Day 39 because I used a max HR of 152 on that run. But now I am only half a minute slower than that time with a HR of 137, so it does seem to be helping my aerobic capacity.

My splits today:
mile 1: 8:12
mile 2: 7:57
mile 3: 8:21
mile 4: 8:45
mile 5: 9:12
HR t+1: 125
HR t+5: 98

I did not get out to the track for my mile, which is probably a good thing given the way my right calf is acting. I would like to see where I am, though, so I will try next weekend. I think I will throw some speed work/intervals into one workout this week as well.
