Yes35,
Most of your statements are incorrect. Canova was not coach of Kirui. Kirui just joined Canova's group for performing a long run. Rgearding the research: I am talking about 400m's . not 1 k's.
And saying that I don't prescribe endurance runs for marathon of for aerobic development shows that you haven't read the book, or have skipped those parts.
HI coach Jeff, eBook now available via Amazon, Kobo and iTunes (Apple)
CAA, EIM addresses running economy AND the aerobic functioning of the fast-twitch fibers.
Most 'normal' runners got a more or less 50-50 distribution regarding FT and ST. With lots of easy runs you won't stimulate the aerobic FT fibers. Meanwhile it has been scientifically proven that 50-50 runners need more recovery time (Eline Lievens, Gent, Belgium). She confirmed my point of view that 50-50 runners need higher, aerobic paces to get adaptations regarding the aerobic functioning of the FT fibers.
Also, San-Millan (physiologist) said that FT fibers need more training at moderate and fast paces, in order to use lactate and carbo as fuels (fins his graph on the internet).
Hi Raw, I also did that. Up to 10x1000m.
Sometimes 1000's in the morning and 200's in the late afternoon/evening.
I give these options in the book
