This 12-week long-distance Build-Peak plan was designed by Joe Friel using the principles from The Triathlete’s Training Bible 5th edition (2024). Having this book handy will help with many of the workouts presented in the training plan and is strongly recommended.

Who is this plan for?

This challenging training plan is intended for an intermediate triathlete under age 50. The plan uses common triathlon language to describe the workouts and is easy to follow.

When should you start the plan?

Start this plan exactly 12 weeks before your race weekend. You should have completed a Base training period and be able to swim 1 hour, bike 3 hours, and run 2 hours in separate workouts. You should have completed at least one long-distance race and have a goal of improving your personal best race time or finishing strongly. Your training zones should be established before beginning this plan. (For a detailed description of how to set your zones for heart rate, power, or pace, read this.)

What is the weekly volume?

Weekly volume is 15–17 hours per week. Recovery weeks, which are every third week, and pre-race taper weeks are considerably less demanding.

Do you need any devices or apps?

You must have a power meter for bike workouts. Run workout intensities are mostly heart rate–based with occasional options calling for goal race pace or effort. Swim workout intensities are based on T-times (pace per 100) or perceived exertion. The workouts were created using the TrainingPeaks “Workout Builder” format so that they may be uploaded to a device (power meter, heart rate monitor, indoor trainer, etc.) or app to help you follow them precisely. (For more information on compatible devices and apps and how to export the workouts, read this. However, it’s not necessary to upload the workouts in order to use this plan.)
