The 100w increase was just to put some easy numbers. I understand all of what you are saying and it does makes sense, as it was what coach told me. My doubt for you and my coach is that if I raise my FTP from the currently 295w to whatever number in the next three months, then the power zones I will be training for 6 months till the next IM race will be higher. Then on those 6 months of training on those new zones I will develop a “higher floor”.
I know raising FTP is hard and sometimes you just hit that roof of progression in which raising it 1 single watt would mean to devote months of work. I just know that I’ve been in 320 doing just Sweet Spot Base I and II mid volume. No Build plan has been carried out by me, thats when the “no one knows your body better than you” statment comes into play.
Thats due to my experience which is evolving from a recreational triathlete to a competitive one so lot’s of books to go over.
Any recomendations to get into Lactate Threshold (books, articles, videos, etc.) would be highly appreciated, as well as all of your points of view.
