Half Distance Training Plan

The Half Distance plan is available in 18- to 21-week versions. It comes in 4 levels, Level 0 through Level 3, so choose the volume tier you can sustain. Pricing starts at $89.95 on TrainingPeaks, or it's included with Team 80/20.

The 80/20 intensity balance applies to your combined swim, bike, and run time: about 80 percent of it at low intensity. That discipline matters even more in triathlon than in single-sport training, because three sports give you three chances a day to accidentally train too hard.

Your choice, per sport. Versions are available combining heart rate, pace, and power — for example run pace with bike power. Pick the combination matching the devices you train with; the session structure is the same in every version.

Levels are weekly-volume tiers, from Level 0 for first-timers to Level 3 for high-volume competitive age-groupers. Choose based on the training load you can realistically sustain alongside work and life — the plan works when you complete it, not when it impresses you on paper.

Through TrainingPeaks. After purchase you apply the plan to your TrainingPeaks calendar, and every workout appears with its structure and intensity targets. Workouts sync to most watches and head units, and your completed sessions are scored against the plan automatically.

Yes. Team 80/20 is $16.58/month when paid annually and includes every 80/20 training plan, TrainingPeaks Premium, and Mind of Matt coaching. If you expect to use more than one plan, the membership costs less than buying plans individually.
