I wasn't one of the beta testers but ordered the book on release day based solely off of the author's credibility due to his previous short ebooks and his posts on reddit.
Could have been called "Canova for Casuals."
It's too late in my marathon build right now to switch plans but there's a ton of helpful information in here if you are on another plan.
For me, a 3:00-3:30 casual, zero-talent, Hanson's guy, the only thing that is scary is that the long runs look pretty intimidating. I think in the spring, I'll probably run the Wind plan (level 2, 50-60mpw) with Breeze plan (level 1) long runs.
The midweek stuff looks very easy, and there isn't epic midweek runs like Pfitz, if time constraints during the week are a thing for you, this is huge.
You can get summaries of the plans at (the book has much more information in the plans section including ... and this is pretty unique ... a weekly coach's note about how you should be doing/feeling each week).
https://marathonexcellence.com/plansOne thing that stuck out to my a lot is the "5k crash course", a way to get back into workouts quickly after a period of easy mileage. This is going to be really helpful to me after the summer.
I do wish the book had an index, that would be pretty helpful. It is a massive tome with a lot of information in different places (though written very well).
Interestingly, it's self-published, but beats Human Kinetics and Velo Press in terms of typesetting and print quality. There's a mention about "RW Publishing" on the imprint page. I hope this means there's more coming.
