So, I’m a bit concerned my cTHR isn’t quite right or that I don’t understand what this really is.
So on Dec 2nd I did a FF and my cTHR was set at 159bpm.
On Dec 21st after completing a Tempo block did another FF cTHR was set at 165bpm
On Jan 4th as part of my ToS prep plan I did HM and it set my cTHR at 179.
I can guarantee you there is a 0% chance that I could ride with a heart rate at 179 for more than 10 minutes.
So every time I ride, I rarely ever hit zone 5 ( >179). If I do it is for a couple seconds and I literally get dizzy if I stay here for more than 30 seconds.
I’m concerned my cTHR heart rate is artificially high and that drags my Zone levels up to artificially high levels.
For instance: on Violator and UAE:1 my average heart rate was 163 which were the two hardest rides I have done in the last few months. I cannot imagine going any harder than this ever. Both of those were 1 hour rides.
163 is consider the beginning of the middle of my ZONE 3 Tempo heart rate zone, which is supposed to be a Tempo ride that I could sustain for a few hours, after 1 hour on each of these rides I needed help off the bike and up the stairs.
- is it possible my HM gave me a elevated cTHR
- how much does heart rate affect my performance measurements within a ride?
- am I right in assuming this is off base?
- if you answered YES to #3, should I adjust this manually until my next FF?
Thanks for your responses and help!
