People learn all their lives. You got in the Hansons team at a point when they probably were very excited about a recent "proof" of concept.
I said for so many times "this is it, I can't find anything more efficient than what I know already", just because I had a good progress recently. And a few months later to discover something new. Their method was not mature enough when you joined them. Maybe they've changed their ideas in the meantime, but they build a business around that concept, so they can't step back now.
I don't want to be harsh with them, but when someone gets hurt (injured), I feel like I have the right to warn others. As you said, forcing the pace and their periodization model are pretty bad ideas.
In my opinion, the best characteristics for runners are discipline and consistency. You have them both, but you seem to be discouraged by the experience with the Hansons.
The reason I love Zatopek is that he never stopped to search for methods to become a better athlete. He was a modest person. A modest person is not ashamed to learn from others, listen others, or verify if his own concepts are correct. That makes one a stronger person.
If you know what to look for, you can understand one coach's training method in 2-3 months. Every coach may have something original, from psychology and strength training method to attitude towards the sport.
I know you've been focused on ultra running in the past year, which is like changing the sport somehow. I wouldn't give up the standard distances in your place, especially with the good foundation you have.
But you would have to look for ways to improve, even uncharted methods.
Here are a few topics that I found and are not common:
- ways to measure consistency and its impact on performance. By consistency I understand the variation of effort or volume in a period of time. For example, how it impacts running all weekdays between 3-10 miles and on Sunday to run 17 miles? How it can be improved and what's the benefit?
- from the biomechanics perspective, how exactly are the hills improving the performance? Why doing strength at the gym is not as useful as running uphill? Is there any static exercise which simulates uphill running?
- is there any way to optimize the effort in a single training day? Besides running a specific distance, a specific time, a distance at a certain pace, a distance/time at a certain heart rate, is there any other method?
- how long it takes for the muscles to assimilate one training day?
- how can you combine all the above?
I actually found my own answers to those questions, but is not the place to talk about them.
Good luck!
