Something has gone wrong with my training peaks. Looks like since I got my new Garmin Watch, it has started giving me TSS based on power for runs rather than HR or threshold pace zones.
This looks like
265 tss for a 50 min run
Old watch, power doesnt even show against the run activity.
it will be using the watch power against your default threshold power. You can either change the default power, add a run power, or click the box as above to change to rTSS or hrTSS
