I got an issue that my heart rate zones from my Polar device do not match my Zwift power zones at all. Usually, my heart rate is pretty much one zone above what my power would suggest. E.g. if I am riding in Power Zone 2, my Heart rate is in Zone 3. Riding on Zwift was so much fun that I bought and “inhaled” the books “Training with a power meter” and “The cyclist’s training bible” already.
Regarding the heart rate: Maximum heart rate is set up correctly and realistic for my age. (192 bpm)
Zones are default as well.
I’m riding on an Elite Diretto XR-T, which can be mechanically calibrated via adjustment screws (the calibration was perfect straight from scratch) and I’m doing a spindown in Zwift once a week just to be sure the wattage does not drift.
Am I missing something here? Is it my lack of fitness? (New to cycling, just started 3 months ago and the ramp test suggests my FTP is 202)
Or is the test inaccurate and I should do the 20-minute test? If so, I’d be sad, because an FTP of 200 was my first goal. But it doesn’t make sense if I keep spinning in the wrong zones all the time.
I also noticed that sweet spot training on the upper end of zone 3 makes my legs burn and I feel really sore after just 5 minutes at this wattage, with my heart rate being almost in Zone 5. So I guess something is wrong here…
Thanks for any advice!
