Calculating TSS

Hi Strava and Strava Users,

I can't seem to find the TSS calculated anywhere in my data. I do find that a little bit weird as it is pretty straigth forward calculation so it would be nice to have that included.

I have found Strava a Strava TSS Calculator which to me seems like an external tool. Anyone who knows about this tool and its connection with the official Strava application.
Thx
Finn

Hi @FinnYding 

Thanks for posting about this.  We calculate the Training Load by comparing your power during your ride to your FTP and determining how much load you put on your body during the workout. Training Load is a great way to determine how much rest you need after your workouts.

Thanks @Jane - that could work out fine if I was only using Strave. But I would like to use TSS as this is - in my opinion - a more common term and thus comparable across platforms.
Do you have any knowledge about the Strava TSS calculator I mention? Is this a Strava recognized tool?

Hi FinnYDing, the metric is called "Training Load" in Strava and it is calculated similarly to the TSS. The difference is, that it's using the Weighted Average Watts instead of the Normalized Power. The Weighted Average Watts are again similar to the Normalized Power but mostly slightly lower due to more smoothing.

Thx Jan - I’m aware of that Strava has another measure but wasn’t aware of how it was calculated. 
it would nevertheless be nice to have a TSS calculation in Strava as well to be able to use the same measure across platforms.
