This is an 18 week plan which assumes athletes have been active, although not necessarily training. Athletes who are ranked similarly in their age-group throughout the swim, bike and run will find this plan especially helpful. It is also for the intermediate-level triathlete.
This plan takes a balanced approached to training and preparation, understanding the bike and run will be the two biggest factors in your race performance. Some may find that certain sports do not get trained enough, but key factors to performing well have been considered when designing this plan. The plan is great for athletes with a HR monitor, but also those without.
The plan follows a Linear Periodization model which will stress athletes, with recovery periods to allow for proper recovery and adaptation. If athletes follow the workouts as listed and suggested, they will see the benefit of performing at your peak for the half-ironman! If athletes modify the plan, and do not follow the guidelines of the daily workouts, the results may vary.
