Hello fellow cyclists,
I’m a 50-year-old cyclist who’s been riding for a few years now. I’ve been working on improving my FTP and I’m wondering if it’s possible to increase my FTP from 200 to 250 in a year. I’d love to hear your thoughts and experiences. 
FWIW, I’m a 59 year-old cycling “covid baby” (hat tip to the Nero Show). I rode outside for one season before I started structured training. In my first year of structured training (Nov 21 - Nov 22) I raised my FTP 85 watts. But obviously those were newbie gains also. Not sure how far along you are into newbie gains territory.
If you’ve been training for a few years, you probably can’t increase your FTP by 50 watts in a year. If you’ve just been casually riding around with your friends and never did structured training before then maybe you can increase it by 50.
I don’t like ftp number goals because there is no clear path to meet that goal. What if you picked 100 watts - what would you do differently than if you targeted 50 watts?
That is my starting FTP. While I had ridden about 1.5 years when I measured that, the riding was not structured training.
