Running TSS question

[kontrabass]

Hi,
I built my plan with plan builder and after some weeks I noticed that the predicted TSS for running is way off.
For example:

1. two sundays ago I had a 1h50min base run scheduled. Intensity was rpe4 ( rpe6 in description) and planned TSS was 84. I ran it with 153BPM and got a RSS 161 from stryd which is twice the amount TR planned(I use polar vantage m + stryd)
2. Last sunday I had a 50min run with 41TSS planned ( again, planned RPE4, but RPE6 in description). I ran 54 minutes, with average 147BPM and RSS was 90.

So the planned TSS vs stryd RSS are always different by quite a big margin. If I also add swim tss then the planned load is way off. For example if in the weekly plan, cycling TSS made up 3/4 of total, then after adding the running and swimming, I may even get down to 50%.

If you even use logic, then 1h50min run cant be only 84TSS which is basically an easy bike ride.

All I can say is “I get what you are saying.” I don’t know the answer … but at least you have something. Garmin does not give me a TSS for runs. Suppose I can go into TrainingPeaks and see what they do.

I use pace rather than HR to calculate my rTSS based on my 1hr pace

(rTSS rather than hrTSS)

[philip_king]

I use TrainingPeaks and have historically used rTSS and not hrTSS, this makes a huge difference to the numbers and means that they are nor directly comparable to my cycling TSS numbers

I think TR works with hr TSS

In Training Peaks you can View different TSS:
hrTSS calculated with HR zones
TSS calculated with Power Zones
rTSS calculated with Pace zones

my hrTSS is mostly the same as in TR description and TSS with Power a lot higher

Hi there.

If you’re planning your training by RPE, you need to execute it by RPE.

So you can either use your stryde as a guide for RPE, or plan your run training for stryde numbers.

[fl33tStA]

Sure, If you can, for me its easier to work with TSS (Power), you can create easily with Training Peaks Workout builder, nearly Same as TR Bike Workouts

@WildWill

use pace rather than HR to calculate my rTSS based on my 1h

Im not using either, Stryd uses power.

edit:
I guess there was some misunderstanding.
Stryd uses power to get TSS, just as in cycling. Not related to hrTSS and RPE. I posted the RPE values just to give some example of the required pace. For example, if the description says RPE6, then i run at 280-315w range and my HR is somewhere around 150.

I play a 40min basketball game, i have no idea what the TSS is. But half the time I cant breath so I score it like vo2 work

Is it your Stryd that is reporting the TSS, or is it Stryd data as viewed in something like TrainingPeaks? I do not own a Stryd, but when I was using the Garmin Running Power function on my FR935 it was doubling my TSS as viewed in TrainingPeaks, until I set my power zones in TP.

I found a lot of inconsistencies between what was described and what the default entry was in the calendar. I reported it at one point but I guess running/triathletes is not high on their priorities now. Maybe it’ll change once they actually start using a tri plan

I have never used a Stryd to get a run-based TSS, but when I was running regularly and using pace as my evaluation factor, my rTSS came in pretty regularly ~10TSS/ mile. 4 mile run = ~40 rTSS. For the mot part, I found those values in the same ballpark as my TSS from a bike ride of similar time / effort.

While Stryd uses power, I know there are a lot of variables they use to evaluate power…I don’t know if watts from on run on Stryd is the same watts as those actually measured via strain gauges on a power meter.

Was wondering a bit on this same topic and glad I found this rather than posting a new comment. I’m currently using Plan Builder with my A race of Santa Cruz 70.3 1/2 triathlon in September. I’m following the 1/2 Triathlon build in Trainer Road and write them into my Training Peak calendar to chart my progress. I use Garmin 920xt and Stryd power meter for runs. When I input the run workouts such as base run w/ 8 1m Anaerobic repeats for a total of 1 hour using the RPE shown my expected TSS score is much lower than the TR TSS expected. In order to adjust my run to meet that TSS score I have to increase the power/ pace of my warm up time and cool down times between the VO2 intervals or lengthen those times significantly, or both. I feel that matching the TSS is most important. Seems like others have had similar difficulties.
