I don't mind at all. In Lydiard's first book, the 1962 edition of Run to the Top, chapter 12 describes the concept of fractional efforts, and gives Tables of Efforts for 220 yds, 440 yds, 880 yds, 1 mile, 2 miles, 3 miles, and 6 miles. He didn't include 10 miles, and might not go far enough for slower runners (or today's fastest runners) but it's not difficult to extrapolate to other distances and times.So although the concept of fractional efforts may seem "fuzzy" and undefined at first glance, to the unlearned, these tables, published in 1962, actually give exact paces for these fractional efforts, based on the distance, and an average of your best times at that distance.But this book is hard to find, and I've never seen tables published anywhere else, so it's not hard to understand why more people don't know about them.I also wonder if the reason it's undefined is more philosophical, in teaching the athlete what it should feel like, or it might change depending in the athlete in question (hmmm, another facet of training individualization?), or because the exact pace doesn't matter for longer aerobic runs, nor for Lydiard's approach to interval training, so very little effort is spent trying to define an exact pace for the fractional efforts. Paces are important for time trials, but here the mechanism to define the paces is very well described, and not with fractional efforts.For the 800m runner in 1:44, the table would give:3/4 effort - 1:501/2 effort - 1:551/4 effort - 2:00Contrary to Antonio's suggestion, I've never seen a Lydiard example of 200m reps at 3/4 800m effort. It would simply be 200m at 3/4 effort.800m at 3/4 effort is a time trial. I can't imagine Lydiard, (or anyone except maybe Bruce Denton) telling you to do something like 8x800m 6 seconds slower than your race pace, although after a quick look, I did find examples of 6x440 yds at 3/4 effort (3 seconds slower, or up to 5 seconds slower if your best is only 64 seconds or slower), and 6x880 yds at 1/4 effort, and 3x880 yds at 1/4, then 1/2, then 3/4 effort.Regarding "repetitions" versus "intervals", I think HRE answered it before. I'm not so sure, but my understanding is that Lydiard called the work-bout the "repetition", and the recovery the "interval". He would call the whole workout "repetitions", unless specifying the recovery interval was important, then he would call that "interval training". I only see "repetitions" in his schedules though, since his idea of interval training was usually "run one, jog one", and he didn't really experiment with recovery intervals, but only advised against making them too short.

Hi rekrunner:
Would you mind giving a range of paces for, say a 1:44 guy like Snell, in that workout example of 3/4 effort repetitions of 800 meters? And in your understanding did Lydiard make a distinction between repetitions and intervals? When you wrote above, in part, "And I'm not so sure that any kind of interval training would ever be done at 3/4 effort" does that mean that there is no such Lydiard workout as 3/4 effort repetitions of 800 meters? Thanks.
