Ready to lay the ultimate foundation for your best Half-IM yet? This 10-week Base Training Plan is designed for dedicated triathletes ready to build unstoppable aerobic endurance and sport-specific strength without burning out.

Is This Plan For You?

If you have big race dreams but struggle to balance a demanding training load with real-life commitments, this plan is your roadmap. Base training is the most critical phase of your year—skip it, and you plateau; nail it, and you prepare your body for the heavy volume and intensity of race season. We’ve removed the guesswork with highly structured, adaptable workouts so you can step away from the stress of planning and just focus on doing the work.

Your Training Benefits

• Smart, Progressive Scaling: 10 weeks of intelligent volume building (starting at ~10 hours and peaking at ~15.5 hours) designed to safely maximize your aerobic engine.
