They just list the 3 hard work-outs, you perform them sometime during the week. I'd have a hard time believing that Daniels would suggest back-to-back hard workouts. My experience is that he tends to list the 2 important workouts of the week and you schedule what to do in the remaining 5 days whether it be nothing, running easy, or cross-training. So with 3 hard workouts, you figure out what you want to do with the 4 days.<br><br>
Although, I "do" think your perception is correct that the workouts, intensities, etc. were developed by working with younger runners, and personally I started doing what Ziggy suggested as use them more as a guidline, knowing already what my own strengths and weaknesses are. (I definitely could not hit the R paces or I paces that I probably could have when I ran track in high school)<br><br>
That said, I do remember reading that some coaches "believe" that their kids perform best with racing back-to-back and maybe this is getting incorporated. Unless Daniels' has changed and adhered to this philosophy, I'm pretty sure he means for you to do one of the workouts suggested, take 1-2 easy days and do the second hard workout of the week, another 1-2 days, hard workout. Listing just key workouts gives more flexibility for you to schedule your week, or if after a hard workout, you don't feel on.....take 3 days off. When your day to day schedules are given, people tend "not" to sway, even when their bodies say "don't run hard, you need an extra recovery day"
