The Power of Scientific, Adaptive Training Theron's proprietary algorithm doesn't just look at yesterday's ride. It analyzes the complete picture, including your health markers, sleep quality, training readiness, and long-term progress toward your race goal.

Intelligent Readiness: We use your Apple Health data (HRV, Sleep, Activity) to dynamically adjust today's intensity or duration. If you're fatigued, Theron gives you an easier session.

Scientific Foundation: Training protocols are based on peer-reviewed sports science to ensure optimal periodization and peaking for your target race.

Dynamic Plan Adjustments: Missed a swim? Your plan immediately restructures your weekly schedule to ensure you stay on track without double-counting or unnecessary stress.

Find Your Race, Build Your Plan Search our race catalog by franchise (Ironman, T100, Challenge, Xterra and more), discipline (Sprint, Olympic, 70.3, T100, or Full Distance), and continent, or add any custom race.
