Keith, The TSS system is built upon the premise that 60 min of maximum effort = 100TSS. Sounds like you did 28 min of high intensity work + 32 min of WU and Cooldown etc. I would expect a high TSS for this but probably something short of 100. My guess is that in the settings your “threshold heart rate” (top left box) is set to low. This should be your anaerobic threshold number which for most folks is probably 150 to 170, this is what training peaks uses to calculate heart rate based TSS and if the number is to low than it over estimates it.
Today I completed a Z3 interval training block. The plan prescribes 2×14 (5min), plus warmup and cooldown; 58 min, with a TSS of 53. My actual time and TSS were 60 min and 100.
Is there any significance to me exceeding the TSS by almost 100%? Something I need to change? Am I possibly working too hard in warmup or cooldown? Is it “good” or “bad” to overshoot this much?
