TSS for a Specific Workout

    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?
    Thanks, Keith

    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.

    Mark,

    I’ve added a screenshot in my settings. The number I’ve entered for “Threshold” is my AeT.
    If I’m in the right area of TP, this should be my AnT (151)?
    If I do change the number, will it change my history (if not I’m assuming I’ll need to see how CTL changes over the next 6 weeks to establish a new baseline)?

    Thanks again, Keith

    Ahh yes, the threshold value should be your ANaerobic value, which in this case is 151. There is an option within TP to go back and recalculate TSS values.

    Keith, Yes if you go under Dashboard>>>Performance Management Chart and click on the 3 line icon pulldown menu you will find a recalculate TSS button. This we recalculate all the workouts that use hrTSS but will not affect rTSS or tTSS sessions.

    Mark, That seemed to work. It adjusted the workout referenced above from 100 to 60.
    My ego is busted – CTL dropped about 30%!

    As always, Thanks.
    Keith
