Wow - I'm blown away. Because I have never seen published data on how elite athletes actually train, I've always assumed it was a trade secret. I mean, I've you're a winner and you hope to repeat, why would you tell everyone exactly what you did to achieve your results?

I think he states quite positively that the proportions stay the same at the 8 hour level as at the 20 hour level.

I'm busily trying to figure out how to apply this to my training. That's not so easy, because it means cutting out a lot of the fun stuff, like long sweet spot climbs and long paceline runs.

One major omission was that it seemed to me that the exercise zone totals were for training only and excluded competition. If they included competition, I think the competition phase totals would look very, very different.
