So this is a little embarrassing. I purchased a Garmin 50 last May. The 50 because the battery lasts a year, versus 8 hours that the other Garmin with GPS last. I mainly wanted it as a pacing tool to use at FANS last year, which I did. Worked great. What good is an 8 hour battery going to do me. Really.
I haven't really used it since. I sprayed mosquito spray on the face and it is now all scratchy, but still readable. I never took the heart rate monitor out of the box or the ANT stick until today..over a year later. Yeah.
This morning Topaz and I ran our usual 5 fun miles on the trail, taking it easy, knowing I was going to try my first tempo run this afternoon. I took out my Garmin box and read the instructions for the heart rate monitor and the foot pod as it has been forever since I used the foot pod. Of course the watch shows a low battery signal. No matter, I was taking it for a spin as soon as I dropped off Tyler at work.
I looked up a quickie heart rate calculation at Runners World. By plugging in my last 5K race pace, last month at the Princeton 5K at 26 minutes I came up with a tempo run at 8:33 minute mile pace. Don't laugh. I'm not real fast. For the max heart rate I did the 220-44 and came up with 176. Ta da. Now this should be my max heart rate. Well, after my tempo run today there is no freaking way that 176 is max for me.
I'll have to try the method of running 3x800, 1 200 recovery and another 400 full boar to figure out max heart rate I guess. (I should have brought this along with me when I ran at the track on Tuesday. Yes! Another track workout; this time all 800s :) I read this somewhere, is this a good enough way to figure max heart rate? At least it is more individualized than the standard 220-age. I mean come on. We are all different. Don't tell me all 44 year olds are going to have the same max heart rate.
I ran the certified Big Lake 8K course this afternoon. Apparently I don't know how to toggle between pace from the foot pod and heart rate or the 50 isn't capable of this feat. I was stuck at heart rate and recalled that 156 heart rate would be 'tempo' if 176 was max .
OK, so maybe the 405 with the 8 hour battery would be a good item to purchase for speed workouts. I'm seeing the light.
The first 3 minutes HR was 150 to 171, then stayed 171 to 173 for the next 36 minutes. I saw 176 as I ran up a hill and I wasn't dieing or gasping so I really don't think it was max. 39 minutes for 8K, not full out, just a quick pace that I was able to sustain..but couldn't sustain for an hour and half I'd imagine. 39 minutes was plenty. Now I have a starting point.
How do most of you figure your heart rate? Do you train with a HRM? I'm never too old to learn.
Heading up north to the beautiful Superior Hiking Trail for three days of long slow running with friends. BETA IV!
