Meticulously crafted from the principles laid out in Matt Fitzgerald's best-selling book 80/20 Running, and followup book 80/20 Triathlon, this plan will provide the athlete with the same workout structure used by the most successful triathletes in the world. Each week, cycle, and the complete 19-week plan has been specifically formulated to match the research articulated in Fitzgerald's publications and ensures the triathlete adheres to the 80/20 principle.

This plan is intended for athletes seeking to achieve a specific time goal in their next sprint event and who have previously completed at least one triathlon of any distance or have a strong history in one of the three disciplines. You should be comfortably able to swim, bike, and run for an hour before you begin. The weekly training volume starts at approximately 7.25 hours in Week 1 and peaks at approximately 10.25 hours in Week 13.
