Geoffrey Kirui and Faith Kipyegon you say? Can you verify that? I have seen the program of Kirui and Kipyegon and nothing like the easy interval method?
I'd also question using Kirui as a reference and marketing point for your book. Yes Kirui is/was coached by Piet de Peuter who has used the Verheul Method but I'm not certain he had Kirui use it, due to his relative high profile some solid evidence is needed for that I think.
"Working in collaboration with Dutch coach Piet de Peuter the Kenyan draws up many of his own training plans and says: “I manage myself well. I have a good feel for running.”"
Not saying Kurui isn't using this method, but there isn't any evidence for it other than having a link to Piet de Peuter.
I have the book and it's a great read, just please please don't follow the example of 'Coach JS' on these forums in listing runners who apparently use your method when perhaps they do not.
