This half-distance triathlon plan was designed by Joe Friel using the principles from The Triathlete’s Training Bible. 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 plan is intended for the triathlete new to the half-distance race. It may also be used by the athlete who has not done a long-course race in some time and wants to get back into racing at the half distance. It may be used by either an under- or over-50 athlete. By the end of 12 weeks you will have excellent half-distance race fitness.

When should you start the plan?

The plan is best started 12 weeks prior to your race, and it ends on your race weekend. The last week of the plan organizes the workouts based on which day—Saturday or Sunday—your race is on. Your swim, bike, and run 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 training volume starts at about 10 hours per week and gradually increases over the 12 weeks to a high of about 13 hours in week 10. A typical week includes 3 swims, 3 bikes, 4 runs, and 1 strength workout. There is a rest and recovery week every third week in which training volume is reduced to about 8 hours. At the end of these R&R weeks there is simple testing to gauge progress toward your race goal.

Do you need any devices, apps, or books?

The bike workouts require a power meter (there is also a similarly titled plan that uses heart rate rather than power for the bike). Run workouts are heart rate–based and swim workouts are based on pace per 100. The workouts use the TrainingPeaks “Workout Builder” so that they may be uploaded to a device (power meter, heart rate monitor, indoor trainer, etc.) or an app so that they may be followed precisely during the sessions. (For more information on compatible devices and apps and how to export the workouts, read this.)
To use this plan, you should have a copy of the 5th edition of The Triathlete’s Training Bible (published 2024) as you will be referred to certain portions of the book that are associated with the workouts in the plan. You may purchase the book here.
