Most 70.3 races are lost in the second half of the run. The swim and bike went fine. The athlete had the fitness. What gave way was form, pacing discipline, or both.

Swim sessions use RPE and pace. Bike sessions are structured by heart rate, keeping effort honest regardless of how the legs feel on any given day. Run sessions use heart rate to regulate effort and keep the easy work genuinely easy.

The plan trains three disciplines as one race, not three separate sports bolted together. Bike and run intensity are placed with a specific purpose, and pacing is developed as a skill across the block. Strength work runs throughout rather than disappearing once volume increases.

Suited to athletes who have raced the distance before and want more structure than a previous build gave them. The plan targets the specific weaknesses that usually cost time on race day.

This is a 15-week self-guided training programme delivered through TrainingPeaks, with structured workouts that sync to your Garmin, Wahoo, or compatible device. Email support from the coach who built the plan is included throughout.

If you are unsure whether this plan is right for you, ask before you buy. If it turns out not to be the right fit, I will swap it for a different one at any time, and I can help with suggestions for restructuring sessions to fit your week.
