4.16.13 Track HR Zone Training

Interesting day today.  I took my VO2 Max data and built out my HR Zones last night.  Two things here, I'm not completely sure the test was run to completion so I built two versions to work from.  I am going to start on the basis built from my test.  If I think the run pace does not match the HR Zone, then I will use table number two.  Based on my test this is how my zones were calculated:

ZoneVO2HR
117.6-20.893-109
220.8-24109-117
324-25.6117-125
425.6-28.8125-140
528.8-32140-156

However, from what I have read my max heart rate should be 220 - (age) which would put around 170.  The last measurement on my VO2 test was the highest and I had peaked from a VO2 perspective.  Strangely, the numbers were starting to work back in my direction.  I was not working at max pace and I was asked to stop instead of not being able to go on.  I don't know what to make of this but I did calculate a second table with the assumption that my VO2 could be a little higher with a max HR of 170.  Not relevant for today and I'm not using it at the present time.  I am in a taper mode for the race on Sunday but Jeff gave me a workout based on HR zone:  1 warm up mile, 2x (1200 in Zone 4, 60-90 second recovery), 1 cool down mile.  My data was as follows:

 DistanceTimePace/mi.HR Zone
Warm1 mile8:518:512.8-3.5
1200.8 mile5:477:154.2-4.8
1200.76 mile5:507:454.1-4.5
Cool1 mile8:458:453.5-3.9

The jury is still out for today.  My pacing seems right on for the HR Zone.  I was running a little hot on the first 1200 and the numbers reflect that.  My cool down mile was too fast.  Jeff wants it in high Zone 2.  I'm used to running around 6 miles on track days so it was hard to back off with the light load.  It will be good to know if my pace in certain zones improves over time.  I assume it should, plus this should provide better training data.
