12-Week Triathlon Base + Strength Plan for Senior Athletes 60+. If you're a triathlete over 60, you already know the feeling: you want to push, but you also want to protect. You want to be competitive, but you don't want every hard week to cost you two weeks of recovery. You want structure—but not a plan built for a 30-year-old.

A beginner-friendly 12-week triathlon base training plan covering swim, bike, run, and strength — 4 to 6 hours per week, built around the 3/1 training method. Structure replaces guesswork from day one.
