I don’t have a power meter, so I really appreciate the new HR-based TSS estimate. But at this point, I’ve had several rides where the HR-TSS seems to be completely wrong. I have been trying to report these to the TR team, but I thought it might be helpful to collect them together and to see if I’m alone.
I use a Wahoo HR monitor.
- 8-hour ride, several hard efforts, HR-TSS = 163
- 9-hour ride, HR-TSS = 181
- 8.5-hour ride, HR-TSS = 139
I do have some rides where it looks like the HR-TSS is too high, but I feel these are much more difficult to assess. I only have a handful of 3+ hour rides that do have power data, thanks to my trainer.
