This plan is designed for the beginner Ironman triathlete.
Prior to purchasing this plan, it is recommended that the triathlete have completed several Olympic distance triathlons or the very least, a half-ironman race. The triathlete should be capable of swimming 30-45 mins continuously, cycle 2-3 hours continuously and running 60-90 mins continuously.
If you have a power meter, you can substitute the HR zone for power zone. However, I recommend using HR zone for the long endurance cycle days as fatigue from the week or environmental factors will play a big part in this particular workout.
Additionally, if you have had shoulder issues or not much experience swimming, you may want to replace the swim strength workouts with a form or speed workout. Also, if in the beginning you cannot complete the total swim workout, shorten the main set according to your current fitness. After 4-6 weeks, you should be caught up to the full workouts. Swim intensities using the RPE scale are as follows: 6-11 easy, 12-15 moderate.
Finally, if you are excessively tired from a particular workout, week or training block and need a rest or additional recovery, listen to your body. Take an extra day or three or even a week if that is what it takes. This program is designed so if you miss a few workouts, it won't ruin your training. After all, it doesn't matter how well or fast you can swim, bike or run; if you don't make the start line, it really doesn't matter.
