I moved away from a coach last season to manage my own training - mainly because I enjoy the speed of learning, development and ownership from making mistake after mistake.
I use intervals.icu to manage my training and I also coach a couple of others for free, to speed up my mistake based learning even faster!
Something I have noticed across the training monitoring tools is that they seem to promote and reward increasing training load with a moving average fitness score, despite the saying ‘training makes you weaker, recovery makes you stronger’. Taking rest weeks to allow for effective adaptation is super important, but this requires you to accept a decrease in fitness - which isn’t really true. Maybe instead of fitness, this should be considered ‘tolerance for training load’ or something similar.
Anyway specifically to my question - is there any software, algorithm or piece of maths, that monitors adaptation as fitness by understanding the benefit of rest following increasing training load? CTL/fitness seem quite dangerous to me…
