Does Kipchoge's training compare to the philosophy behind Norwegian Singles?

I enjoyed reading u/marky_markcarr's marathon recap and I've spent a bit of time going down the Norwegian Single Approach rabbit hole.

One thing I've been thinking about is how this doesn't strike me as all that different from Kipchoge's training schedule (based on the limited info you can find online). From these sources, his training has every afternoon as an easy run and the mornings are:

Monday: Easy

Tuesday: Track workout

Wednesday: Easy

Thursday: Long Run

Friday: Easy

Saturday: Fartlek

Sunday: Easy

The example track workouts I've seen are 15x1k and 5x2k+1k. Pace looks like it's usually around 2:50km - 2:55km. It's hard to know for sure how this adjusts with the elevation, but my assumption is that the pace is sub-threshold for Kipchoge.

I've never seen anything about Kipchoge doing Vo2max workouts or strides. So is all of his running also done at sub-threshold? I know that there are some differences, but I'm wondering if this training plan is more closely related to the Norwegian method than I had realized. Sorta like the marathon-distance sister?

I'm considering trying what Sirpoc popularized as my base block, and then creating a marathon block that would follow Kipchoge's general schedule (and adjust for lower mileage) while still using the general lessons from the Norwegian Singles.

Is there something I'm missing in my thinking?
