Let me try this again, and hopefully this is not duplicative. My apologies if so…this seems like as good a spot as any within UA to pose this question –
I have recently suspected that Training Peaks is not providing the same TSS “credit” for similar training sessions, perhaps materially. I completed a trail run that I somewhat frequently run today, and noticed that I ran the same course 5/13/2021. I ran it in 2021 at an average HR of ~134 and today at ~141, today not looking at my watch the entirety of the run, and obviously capping my HR in 2021. My pace on the 5.91 mile course in 2021 was 10:40/mile, whereas today it was 9:10/mile. I finished today almost exactly 9 minutes faster than a year earlier, or 1:30 per mile. HR TSS in 2021 was 82, whereas today it was 65. Caloric expenditure was almost exactly the same.
So, what accounts for the difference in HR TSS? Is Training Peaks trying to kill me as I approach summer intending to be at or above 2021 fitness?
Thanks in advance.
