I just did a quick read and can't say that I could really contribute here because I have the same question as you 400. It would seem as if lactate tolerance work should precede the lactic power work to get much value out of it. Perhaps the terminology is just confusing me. Also, it would seem that the overlap between the lactate power and lactate tolerance workouts would be so great that just simply giving the distances, sets, and reps would not be enough. That is, the intensity / pace of the run would be the key factor to whether a run or workout is considered either lactate power or tolerance work (as they are defined here). Steve (the author) is a member of this list and hopefully he'll comment on these points.
