Is there only one way to periodize triathlon training? Joe Friel’s alternatives

After dedicating two chapters to planning, Friel opens up an important question: what if the model presented isn't the best fit for that athlete?

Chapter 9 shows alternatives and adaptations. Its starting point is that the structure can change, while principles like progression, specificity, reversibility, and individuality continue to guide the work.

Adapting the Model to the Person

The author recognizes the advantages of the linear model, but also discusses its difficulties: time constraints, prolonged repetition of stimuli, and the need to balance disciplines that may progress at different rates.

A model is a way to organize preparation. Its suitability depends on what it allows you to accomplish and the observed response. The chapter does not establish that a more complex alternative is automatically superior.

Friel also highlights the possibility that a structure might work at a certain time and need to be revised later. Preparation involves experimentation accompanied by observation.

When Available Time is the Limiter

One of the adaptations closest to an amateur's life deals with a lack of space in the schedule. The physical capacity to handle more hours doesn't mean those hours are available.

The book discusses redistributing work and, in certain situations, altering the relationship between duration and intensity. These adjustments are presented within a plan, with limits and attention to recovery.

The discussion does not allow for a simple equivalence between minutes removed and effort added. The context remains necessary: the race, the abilities that need to be developed, and what is already in the week.

Concentrated Load Blocks

Friel describes short periods of more concentrated training, called crash periods, followed by recovery. Training camps can serve as an environment for this strategy.

The chapter recognizes that group enthusiasm can lead you beyond what was planned. The possibility of gains comes with the need for control and individual limits.

This summary presents the strategy as part of the book's content, without reproducing load increases or creating a protocol for application. The relevant reasoning is that concentrating stimuli also changes the subsequent recovery demands.

Inverse Weeks and Slower Recovery

Another alternative is to change the order of high- and low-volume weeks. Instead of having the load increase in the same sequence in every block, the author discusses structures that start higher and then decrease.

He also considers shortening the time between recovery breaks. The goal is to adapt the distribution to the speed at which fatigue accumulates and dissipates.

Friel points out that age and experience can influence this discussion, but they alone do not explain the individual response. Recovery history provides more specific information than a classification applied without observation.

Reverse Periodization

In reverse periodization, the relationship between duration and intensity emphases changes compared to the classic linear model. The author discusses its usefulness, especially in the context of long races.

To understand the proposal, it's necessary to uphold the principle of specificity. If the race requires sustaining work for a long time, approaching it might involve giving more space to this demand during the specific period.

The name “reverse” doesn't mean skipping base training or ignoring fundamental abilities. It's about a different organization of emphases throughout the season, discussed by the author for certain scenarios.

Undulating Periodization

Undulating periodization alternates emphases in shorter intervals. Friel presents possibilities for alternating focus between disciplines or between duration and intensity.

In triathlon, one week might favor cycling and another running, while keeping swimming more stable, as in the example discussed in the book. The goal is to create conditions to develop abilities without trying to maximize everything simultaneously.

The alternative still requires moderation. Concentrating focus on one discipline is not the same as making it so demanding that it compromises the rest of the program.

Block Periodization

Friel relates this model especially to very advanced athletes, for whom small gains become difficult. The emphasis is concentrated on a few abilities during a block, while others are maintained.

The author points out that this context should not be generalized to beginners or athletes who still have significant room for improvement with more comprehensive training.

The distinction is important for those who look at elite examples: a structure built over years of development cannot be understood solely by the appearance of the most recent week.

Adjustments Based on Adaptation and a Simple Solution

The chapter also presents the idea of modifying the program according to signs of adaptation. Instead of moving forward just because the calendar marks a new phase, the athlete should observe whether the expected changes have occurred.

In the end, Friel offers a simplification: maintain a routine that fits into your life and have your training progressively approach the race. The level of detail should serve your decisions.

Editorial example: if a structure with too many adjustments makes it impossible to follow your own program, simplifying it can make execution and evaluation easier. The main question remains whether the structure prepares that person for that competition.
