TSS Discrepancy between Zwift and TP

Training Plans
1

I’ve used Zwift’s workout planner to make target intervals to simulate group rides and look to reach the TSS prescribed.

I checked these rides against my TP data and there’s a discrepancy.

186 TSS in Zwift
210 TSS in TP

This happened again today. I was doing PRL Half in Zwift, finished, did the fake exit to check my TSS and saw that I was a bit short so kept doing Z2 until I reached 192TSS.

Once I finished I checked TP and it was 246 TSS.

Anyone else know about this or has experienced this?

On my side has like 5 to 10 TSS discrepancy, whether i load from TP or Zwfit, but it’s not important as long as you put the workout in and give 100% on training.

Part of the obsessions we have as cyclist is numbers.

Sounds like your FTP in Zwift is probably set higher than it is in TP.
