CTL absolute values different from Training Peaks?

[cseilern]

Is there a reason why absolute CTL values very are very different from those in TP? it looks like CTL in % of peak is about right, but absolute values are roughly 2x those of TP.

I had this issue in Intervals.icu too but fixed it by getting correct RHR values or by switching to using Time In HR Zones instead of TRIMP to calculate activity TSS.

Is there a way of making Runalyze CTL close to the same as that in TP?

Check your resting heart rate. Your latest entries looks quite wrong. If you update or delete them, the TRIMP values of the activities won't be updated.
For Garmin e.g. you can disable the sync of the RHR: https://runalyze.com/connect/garmin/settings

Thanks @mipapo, garmin was feeding a few strange data points, and i deleted them and instead getting RHR from Apple Heath which seems to be fine.

But as you said, that does not recalculate activity load values and hence CTL remains unchanged. How can I force a recalc?

https://runalyze.com/my/tools/cleanup -> Loop through activities -> Recalculate TRIMP values

thanks @mipapo, but i already tried that and it made no difference, CTL in Runalyze is still around 2.3x higher than in TP, both now and over time.

But i did notice one thing: in Runalyze, I had a TRIMP of 374 for a ride i did on Sunday, but only a TRIMP of 286 for the same ride in Intervals.icu.

I guess that would explain the differences in CTL between TP and Runalyze (I have the same CTL in TP and Intervals.icu...)

But then why are the TRIMP values so different in Runalyze and Intervals.icu?

[laufhannes]

There are numerous variants for how to calculate TRIMP. We use the exact heart rate histogram - that means not only time in zones but time at every single bpm value - and TRIMPexp from https://fellrnr.com/wiki/TRIMP#TRIMPexp ... te_Scaling which depends on resting/maximum heart rate.

As we are not developing Intervals.icu or TP we can't say anything about their calculation / implementation.

(Are you sure about your max. heart rate set in 2019? https://runalyze.com/health/heart-rate-max/add - sounds a bit less)

Thank you @laufhannes, and thank you for a fantastic platform too!

i did some cleaning up on MHR and RHR and it did improve things, and, all things considered, my CTL chart in TP, and in Intervals now looks the same as the one in Runalyze, even if absolute values remain v different. But I assume that this is because you use exponential TRIMP whereas Intervals and TP do not. I have copied the charts below for you to see.

But I have come across another question as I was fixing all my data: how can I delete entire data sets (in this case all RHR entries)? so that I can force resync all Apple Health data and remove all Garmin data?

You can't. only manually. Get in touch via support chat and we will delete those entries for you

Thank you for all the help guys, I really appreciate it
