How long did it take for you to bring your FTP at altitude up to your previous sea level ftp? I ask because I am likely moving from around 750’ to Denver next summer and I am curious what others who have made a similar move experienced in training, racing, and hard group rides. What was the adaptive period like? Weeks? Months? Years?
I think the podcast said once that 3 weeks you’ll be most of the way there.

That was my experience as well, when I moved from 2000 feet to 7000 feet.
It will never be the same at the same fitness level.
You’ll be extra handicapped for about 3 weeks while you acclimate, but after that you’ll still have a lower FTP.
Here’s a graph showing it. Notice how it’s lower for non-acclimatized vs acclimatized.

But you feel like a beast when you go back to sea level to ride
