Hi Robert – okay great, you are very welcomed. As for your question about jumping ahead some weeks with the advance half ironman program, it should be fine. Just build into the intensity, and focus on getting in the prescribed volume. All the while emphasizing consistency from workout-to-workout, day-to-day and week-to-week.
At the end of the day, the most important factor is how you do things. What you do, and how much you do, is also important, but not as much as the “how” 🙂
