Ready to crush your next Half IM feeling strong, fast, and fully prepared? This comprehensive 19-week plan takes you from building an unstoppable aerobic base straight through to an epic race day, without taking over your life.

Is This Plan For You?

If you are an intermediate triathlete balancing big race-day goals with a busy family and career, this plan is your ultimate roadmap. We’ve eliminated the guesswork so you can simply wake up and execute. Gradually scaling from 9 hours to a peak of just under 13 hours and 45 minutes a week, this schedule is highly adaptable to absorb real-life interruptions. It even builds in strategic tune-up races—a Sprint and a 5150 triathlon—so you can practice your pacing, nutrition, and transitions under real pressure!
