Yesterday, I marked my penultimate training session as Very Hard, instead of the predicted Hard, and the AI FTP dropped my predicted improvement from 258 down to 252 (and I’m currently at 251), so a miserly 1 W increase over 4 weeks of training.
And, I think it’s spot on. As much as I’d like a higher FTP number, I think it gauges my fitness correctly.
I think having the prediction right there in my face every time I open TR has made me less fixated on the actual value, and more reassured that my training plan is properly calibrated to my actual fitness.
Instead, I’ve now become fixated with my Zwift racing score…
