This is all really interesting to me. As an undergraduate student working 15 hours a week, I realistically have a lot of training time, and I've wondered what'd happen if I just kept upping my training time. I've always intuitively liked the idea of lower intensity and higher volume—you get to see more, for one!—and when I was much younger even subscribed to the Maffetone Method of riding aerobically for as much time as I possibly could.

I'm preparing for a couple of sportives this year (Tour of Flanders / L'Etape du Tour) that require me to be in pretty good shape, and what I'm seeing here seems to encourage more time in lower intensities, and more specific and higher intensity workouts in the upper zones. Were it not for the fact that I snapped my derailleur hanger last night and it being a public holiday today, I'd be out now.
