Hello John,
I want to update my FTP after the attached ride but want to make sure the number looks good. Based on the ride, I would like to update the new FTP to 244, however, it didn't feel like it. Can you take a look at the file to see if that would be correct?
As always, keep up that great work and thanks in advance.

Re: Update FTP After Ride
Yes, FTP is high, because your Crr is 0.01...the kind of rolling resistance you might get when riding through sand!
It looks like you have a gravel bike. I am guessing you did your FTP test on a normal road, so I adjusted your Crr down to 0.007. Your FTP drops to about 150W.
Corrected ride file and profile attached.

Re: Update FTP After Ride
Hi John
Could you please explain why one would want to change ftp manually after a ride? As I understand it ftp is a synthetic benchmark that assumes you performed at (nearly) 100% for ALL the time during the test period. Only in a time trial race I could imagine this to be the case (and only if there would be no sharp turns making you break or stop pedaling).
Does changing FTP change anything in the ride stats? Only if I would have a diagram of relative power i guess ("performed at xy % of my max. power)". And a diagram like "power stress score" or thelike I haven´t found in isaac yet.
I guess ftp would be important when training with power house app. And for tracking my progress. But why would I tweak asingle ride?
Cheers
Roger

Re: Update FTP After Ride
I don't think we say, anywhere, that you should update FTP after a ride.
The only reason to update FTP would be:
1) Your PP was incorrectly calibrated at the time of the FTP test; you've corrected the calibration and so FTP needs to be corrected
2) You did a new fitness test, the result of getting stronger on the bike, , and FTP needs updating.
In the case of the post on this thread, the rider had an incorrect Crr setting, so his reported FTP was too high.
