So I forgot to update my ftp after returning from an injury that kept me off the bike for an extended period. Is there any way to go back to these first couple rides and update to a corrected/lowered ftp? I have updated my 920xt to the correct stat and tried re-uploading but thats a no go.
What you want probably can't be done. The system is not designed that way. The FTP setting is recorded with each exercise file as that's what the unit uses for setting zones for each setting.
If you want to try, you could delete the activity on Garmin Connect and re-upload through the website after changing the setting on your 920XT, but my guess is that it will still show the previous setting.
