Thanks Rob, that would make sense. I actually have slightly less time than you (mid August race) so won’t make it through the plan a full two times. I think my approach will be to run through it once with the additional ME workouts in place of the Z3 workouts, and then on the second (truncated) go-through, focus more on the latter half of the plan to get the full effect of the intervals (basically just extending the ME phase overall and then the interval phase overall).
