I read some of the other posts about P1 pedals but not sure they really apply. I have a Wahoo Kickr, P1 pedals and a Garmin 820.
I am sending my data to Strava and Training Peaks (for my trainer). I have found that the wattage on zwift is consistently 20% and sometimes 30% lower than the readings I get on my Garmin with the P1 pedals. I generally load my days training into zwift to apply the resistance necessary. I find that I have to start off riding to see where the difference is for that day then adjust the ftp in the workout to get the desired output on my Garmin.
I can’t use the zwift to document the workout in TP because the readings are consistently lower.
Is there a way to get these units to mesh within a couple %?
