I log my commutes on TR and have been doing so all year.
In the past month I bought a power meter. Also I recently (~5 weeks ago) did an FTP ramp test so my stats should be reasonably up to date.
Before the powermeter I was using RPE to estimate TSS and would typically get 25-30 TSS per commute (it’s not a long commute).
The results from my power meter (powertap P1s if it makes a difference) are now giving me a TSS of 45-50 for the same commute. I’m not putting in harder efforts or better times since buying the power meter.
In order to get anywhere near that TSS I would have to select an RPE of ‘All out’ for the same journey.
What’s going on here? I’ve no reason to doubt my power meter, but how can RPE estimates be so far off?
If I’d have had a power meter all year my TSS from my commute alone would have gone from 200 TSS/week to 400 TSS/week!
Any insight? Commute is only 11km so is it fair to say that RPE method is more inaccurate for short distances?
