Workout: Run 30 Minutes on the Treadmill – Knee is Still an Issue
Posted on March 25th, 2010 in Run Log, Workout Log | 6 Comments »
I took Jeff’s advice and ran on the treadmill to give myself a easier surface on which to run. Its good advice. While I don’t particularly care to run indoors, the surface is more forgiving on my knee. I wore my HRM strap today. The cool thing about my Polar HRM chest strap is that the treadmill at the gym actually picks up the signal and displays my heart rate on the console. I don’t even have to wear my watch. I had a pretty good session. I didn’t push too hard. My goal for now is to build my base.
According to the HR formulas, the aerobic zone for my age is 127 bpm. Honestly, it is not difficult for me to hit 127. Shoot, my heart rate spikes way over that when they flash Nancy Pelosi’s face on Fox News. All the articles say that one should not be tempted to go over the aerobic zone (127 for me) while base training. They say just stick to the program and it will make me a better runner. Heck, I could not keep my HR below 127 no matter how slow I ran today. Further, my knee is still having issues so I don’t have very good running form. I tend to favor the knee and run with a sort of unbalanced stride. I am sure that alone is good for a few more bpms! Anyway, I feel more comfortable running around 135 – 140. According to the MAX HR formulas, my max is supposed to be 167. Of course, the generic formulas are not accurate. Last summer when I was running quite a bit, I sustained heart rates above this number. I know the only way to get a good number is to go and get cardiac stress test or a VO2 Max test. I suspect my max HR is really around 178 to 182 (just a guess). So I will be building my base using RPE, although I will wear my HRM just for correlation. I am tempted to go balls to the walls on my bike and see if I can top out my HR and sustain it for a while to determine my max. I am not sure that is a good measurement, but it is probably better than the general formula.
Here is a self test for finding my max HR…

I’m with you on the aerobic, anaerobic and max HR formulas — bunch of crapola. I have not ran or biked with a HR strap since January. I basically decided that the readings were too erratic. I mean they would change dramatically from morning to evening workouts. AND my max is supposed to be in the mid 190′s and I have hit in the mid-200s and still had more to give? So, I dumped it and couldn’t even tell you where the HR strap is to my garmin is? RPE works best for me.
Jeff… Ever since the marathon training and injuries, running is a real chore. I knew I was over-doing it when I was training, but I am stubborn. At my age, I just don’t recover like I used (read as “enjoy your 30′s and stay strong). Anyhow, the knee is still bothersome. I toyed with the idea of doing a triathlon this summer, however, I may have to re-think that and work on my base and rehab the knee and try next year. I really want to nail my aerobic zone… RPE seems to be what I need to use.
HAHA loved the Nancy Pelosi comment!
And I’m like you with my Polar (talk about fitness gadget overload: HRM, bodybugg, pedometer… I have it all!). I can’t stay below my recommended aerobic zone either.
Good to know it’s not just my Polar.
Annie… I also have a body bugg!!! All these gadgets and I still can’t run like the wind!
Have you considered a proper diet for your knee pain?
Hi Quentin… Yeah, I am trying to watch my nutrition, especially trying to lose a few pounds to take the weight of the knee.
