Subject: Zone Training - Too Hard? I have a question about zones based of HR. Are these efforts too hard?
For reference, I took a LT test several weeks ago and it was determined to be at 166. I did a field test with similar results. Using LT or Max HR, my running zones are as follows:
HR/Pace label Range data label Time
1 - Recovery 110 - 141
2 - Extensive Endurance 142 - 151
3 - Intensive Endurance 152 - 158
4 - Sub-Threshold 159 - 165
5a - SuperThreshold 166 - 169
5b - Anaerobic Endurance 170 - 175
5c - Power 176 - 184
Be Iron Fit Run Zone:
Z1 118-135
Z2 137-155
Z3 157-162
Z4 164-174
My running Z2 HR range, based off several methodologies, is around 140-155 (Fink, Friel, MaxHR, etc. ). The thing is, to get to low Z2, I am in the 6:50-7:15 min/mi range. I can and have been running in these ranges, but just wonder if it'd be better to run easy some days, hard others, and not worry about zones...
Could I get some feedback from any of you savvy HR training folks?
Thanks! |
