Método Hanson de entrenamiento para maratón (Running)

The book emphasizes a different structure compared to traditional marathon plans. I'm curious what led to this particular methodology and how the author developed it.

I wonder if the plan works well for both beginners and more experienced runners, or if it’s tailored to a specific level. Has anyone modified it successfully?

The balance between long runs, speed work, and recovery seems carefully calibrated. I wonder what the decision-making process was behind these choices.
