I agree with much of this. The system/process and the psychology are what have made FM amazing. So those kids reach more of their (a higher percentage of) potential in hs. In college, they don't have the same system/process. They don't have the same leadership from within the team or above the team. The coaching and team environments are absolutely foreign to what they have experienced in hs. Everything they used to build their success, physically, mentally, environmentally, socially, etc. is gone in college. Running isn't just running. It is far more complex than that.
Most college coaches, especially in the P5 world, are very mediocre. When you automatically get the top kids in the country year after recruiting year because of your school name, you don't have to be a great coach to have a fast team. There is no incentive to change either. If runners come in and don't perform, someone from the next recruiting class will take their place. Most college coaches don't show much care for their athletes personally either. Based on the reading, most college coaches are around/interacting with their athletes less than 10% of what Aris does with his FM athletes. Imagine getting 90% less attention and care from your coach after 4-years (formative years) of complete attention in high school (and more at FM since they often join the team in 7th or 8th grade).
Most team environments in college, especially in the P5 world, are very individual. There is very little accountability. You do it primarily for yourself, which is the exact and complete opposite of why you do it at FM.
If FM runners don't improve much or at all at the collegiate level (and I have no idea if they do or not), that really should be no surprise. The entire system that brought out a higher percentage of their maximum ability in hs is gone. It would be very reasonable to expect the improvement to decline or stop. The pressure would actually go from not eating crap and to doing everything right, to having fun and not making others feel bad. From the norm being extreme commitment to no real structure at all.
There is something amazing about being part of a group that is completely unified in pursuit of rare excellence. It is worth it. A person will usually rise much higher for others than for themselves. That goes away in most collegiate programs. Further, the closer to your maximum the smaller the improvement margins anyway. And I agree with several on here who have said that most kids do not improve in college. That is the norm.
I don't think you can simply say that they are "burnt out" from their hs training and system. The "burn out" or less than expected performances would be just as reasonably attributed to a new system that is disappointing and lacks motivation, accountability, team spirit and sacrifice, and coaching that is just business, rather than coaching that, albeit could be labeled harsh and consumed, both seems to truly care and is about building people through the act of running. Everything they know and everything that has contributed to their success is gone. They have to reinvent themselves or fade off. The whole purpose and process of running is no longer there to support them.
To that end, the one criticism I would then have (I've read more than half the book so far), and it is actually a small criticism as I don't know it's a reasonable expectation, would be that Aris's grand plan was to teach Stotan ideals, to use the sport of running to teach and establish those ideals in their total lives and all around thinking, and to see what the results could be. While the results within the program athletically speak for themselves, it would seem (not unreasonably) that the Stotan ideals mostly remained with the FM program when the runners left to go out into the real world. The Stotan ideals seem to work primarily in the insulated, saturated and fully accountability environment of the FM program, and are not sustained in a significant way as individuals outside of that bubble. Thus, maybe the experiment is a failure, if the goal was long term transformation of thinking and lifestyle.
My last thought is, I think really Aris benefit's from implementing this program and philosophy near the year 2000. Based on generational changes and our current culture I think if he were to try to start this same system and style of coaching today, from scratch, he would be obliterated and run out of town as an egotistical, abusive, evil coach. Not saying any of that is true (I don't believe it is), but it doesn't have to be these days. I've seen successful and caring coaches expect far less and act far less demanding get blasted in recent years. He is able to continue (for now) because he already established this culture at a time when it would still be accepted, then delivered on incredible results that everyone wants a part of. I would strongly advise any coaches out there who would consider implementing a program very similar to Aris (and his style...yelling, carrying a big stick, calling kids out in public, the whole extreme tough love style) to not do it. Unless you are ok being run out of coaching, because that is the most likely outcome. It just doesn't work in this culture at this time.
Thus, to me this is an interesting book about a pretty cool philosophy and a very interesting personality that works in one specific environment from a specific time and is unlikely to work anywhere else in this time and age. Enjoy the story and maybe glean a few nuggets, then move on.
