Hi Brian,
thank you very much for your reply! You are absolutely right, lots of context is missing and I am completely aware of it. The reason is that I do not want to make this a personal thread about me (I think this would belong in a private coaching session). I rather wanted to reach out to the evoke endurance community, share my experiences with negative drift and maybe find people that made similar observations.
My last post was meant to share what I found out, namely that I see a linear negative drift for slow paces and a kind of negative logarithm shape when I am not recovered. And if I go too fast, my drift is positive of course.
Have you ever observed negative heart rate drift in your training?
Kind regards
Christian
