But maybe return stronger and slightly less hard???? The (almost entire) absence of physical injury does not mean that he's not doing a real number on his hormonal health and adrenal system. Think of Ryan Hall's essentially forced retirement as an example. The body cannot just hammer huge mileage combined with frequent high intensity with basically no rest. Jake explicitly said on his livestream post-Valenica that Suguru Osako is such an outlier setting the Japanese NR because most Japanese runners retire at age 25... yet there he goes copying Japanese training plans from decades ago.
He then mentioned that he continues to pummel himself into the ground because he is convinced that this "run through a brick wall" approach is the only way he has been able to run even under 2:20... as a blanket response to criticism about his training. But how does he definitively know a change to a more sustainable methodology will be unsuccessful (especially when layered on top of a huge aerobic base)? Obviously the iron (and/or additional still undiagnosed) health problem(s) are/is an additional issue but that's a symptom of the crazy mileage rather than the sole cause for the in-race blackout.
He absolutely buried himself on Sunday in a way few of us will ever experience and which will take a sizable amount of time from which to recover yet he wants to race at least three more hard efforts this year. That is objectively insane (yet nevertheless applauded by his viewers because his channel is fun and engaging). But, think if this was a woman influencer/ runner. EVERYONE would be up in arms about "exercise addiction" and "unhealthy compulsion," and "likely eating problems" (for good measure). I'm not saying Jake exhibits any of these issues necessarily but it's an interesting thought experiment.
And, yes, I love the channel and have watched each video from the early days.
