you said it. there is a paradigm shift. all bets are off. jacob was quite enough of a game changer, and now we have laros, myers, ruthe, and who else?
personally i need to recalibrate, as the old formula of doping, progressions, training, etc. something has fundamentally changed, shoes, tracks bicarb, amino acids, traning the gambit, i do not have a handle on it, formerly i would be comfortable in commentary, based on the fundamentals from coaches of note, with minimal novelty from this side.
some of this was predicted by percy cerutty, and actually arch jelley, coach of john walker, though i can't speak for them, the way it is playing out, maybe not what they envisioned.
you can google arch jelley on his 101 year birthday about snell, advances, and equivalent times back in the day.
and maybe read about percy cerutti predictions from his books back in the day.
every evolving Gault, can supplement his learnings with the above. he's close to the premier journalist already, with few holes , being subtleties in elite training and certanily insider ped know how.
also really required reading is the books by gordon pirie, he was quite the guy, nuts somewhat, with come fundamentals, which are expressed, i think in today's shoes.
there you go
