I have always had a problem with Strava underreporting power for outdoor rides. I use a wahoo ELEMNT bolt v1 and a Quarq D-four power meter, training peaks and the ELEMNT app have always aligned but Strava has always been 10-20 watts off the average and sometimes up to 200 watts off peak power.
But I don’t rate Strava so it has only become an issue now that I am trying to use the AI FTP detection function and with my current set up Strava is the only way to upload outdoor ride data to Trainerroad, and I am doing all of my training outdoors at the moment.
Is there a work around for this to ensure accurate data is transferred over?
Likewise is there a simple equipment change that will negate this calculation error by strava?
