Yea, that would be my instinct and it’s what I’ve done before. Problem is I’ve now gotten hooked on indoor ramp test and that would be a tough one to do outside to compare! So then I’d have a possible testing offset too…
The first year on TR I used an 8-min test outdoor FTP on indoor rides and it was pretty brutal - I’m pretty sure I’d get at least 10W difference if I could match the tests perfectly.
I also wasn’t sure what the technical consensus is these days for what is “right” from a TSS/training load perspective.
In my case, a watt is always a watt since I’m using same power meter indoors/out so that uncertainty is gone, but if hypothetical matched FTP test result is still different in that scenario, do we scale the outdoor ride to higher watts, or keep the same target and accept that it just feels easier because the environment is different, and that’s why we see differences in HR, RPE at same wattage?
I lean towards raise the outdoor targets to match HR and RPE - but that also seems to go against the mindset that power is the most unbiased metric and should be trusted over HR/RPE.
It’s a circular rabbit hole… maybe I should just go ride my bike
