I’ve seen a lot of threads on power differences - most seem to involve smart trainers. I don’t have one - just a ‘dumb’ Kenetic fluid trainer and PowerTap P1 pedals.
I recently discovered that my TR App is showing watts anywhere from 10 to 18 watts higher than my Garmin. I thought (was hoping) that it was an issue with my Garmin until i borrowed a Wahoo element bolt today. Running all three at the same time - TR App, Garmin and Wahoo Element Bolt. The Wahoo and the Garmin agreed, my TR App still read high. Was running 3 second smoothing on all three.
All of my training progression is tied to TR - so its relative to me, but i use my Garmin on my outdoor rides…no wonder it feels ‘harder’ outside.
Is there a power match thing i am supposed to do? Something else obvious that I am missing?
