Important discussion – let’s see what we get out of all this for the next year, i.e., 2027😉
I have tried a few of the floating LLM-based “coaches” and some keep sending me info, analysis, planning emails. Sometimes useful reflections I take into consideration.
Moreover, I do have an active athletic.ai subscription because that provides me a good base for my short-term (1–4 weeks) training plan including tapering for races, etc. I’ve also copied some of its recovery arithmetics to intervals.icu, for instance in the (public) “HRV profile” or “rHR profile” charts…
I also have an opinion on how an AI coach should work for me, but I really want much more than a general LLM or a Pareto-fulfilling GPT behind …
For now, I am continuing with a “natural intelligence” (me) adjusted version of the atheltica.ai plan, because it is convenient, esp. regarding my time restrictions. I want to spend time on the bike, not thinking about time on the bike. And I adjust based on feel and some simple plots like the standard ones in intervals.icu and the added ones above… 
But I am also sure that LLMs and agents will provide a lot more – also to training – in the very near future:-)
