Everything Is Photogenic

For those who train indoors and outdoors, tell me how your FTP/Power profile compares indoors to outdoors:

My HR is a lot lower at low power range indoors. Yet power meters read only a few W different. I have always put this down to the additional stress factors like alertness, temperature and other cognitive load factors of riding outside.

On a typical Zwift ride my average Watts is, say, 307. Outdoors, 240. But I have hills and traffic and things outdoors. Also, on Zwift, my heartbeat rarely rises above, say, 135. Outdoors easily goes to 160s when I push it.

Outdoors is higher. But the extent to which my outdoor power is above my indoor power is confounded by differing power devices - indoor its my trainer and I know the drive train on the old bike attached to it is inefficient (I can hear that!) and power is measured at the rear axle via the trainer - outdoors I have Faverro Assioma power meter pedals so drive train losses aren't a factor (though my outdoor bike is set up well and chain waxed etc) so the extent of the discrepancy between the two is hard to quantify. But it is there for sure.

No power meter outdoors so I don’t really know.

Instructions unclear - can't confirm. What I do know is that I push myself way harder indoors, especially when racing.

It's been so long since I've trained both ways; now, I'm just an outsider.

id say 10w more outside. me thinks better cooling and higher oxygen ppm is the big ones for me. using same PM so drive train loss isnt a factor
