DEVELOPMENT BUILD • AI TRAINING SYSTEM
An adaptive training companion in active development — built from Ironman and marathon cycles, grounded in HRV and recovery science, and engineered to evolve with every block of training.
Development phase: Active Build
System
AI PACER separates what happens during the session from how your body recovers afterward. Real-time metrics guide the moment. HRV and trends guide the plan.
Real-time metrics
During the session, AI PACER responds to what you’re doing right now — effort, pacing, and execution.
HRV over time
HRV doesn’t change second-to-second. It shows how your nervous system is adapting across days and weeks.
Guided by recovery, not ego
Real-time data shapes the session. HRV and long-term trends shape the training architecture.
Build in public
A working record of how AI PACER is evolving — combining endurance racing experience, HRV education, and real-world physiology.
Separated real-time session engine from HRV-driven recovery model.
Added 7-day HRV trend into block planning recommendations.
Adaptive pacing loop tuned for mixed indoor / outdoor sessions.
Signal map defined — HR, pace, RPE, sleep, and HRV for long-term adaptation.
Human + machine
AI PACER comes out of long-course training — Ironman, marathons, fatigue, overreaching, and the reality that recovery matters more than any single workout.
As an endurance athlete with HRV training, I learned that the most important metric isn’t how hard you can go today — it’s how consistently you can come back tomorrow. HRV became the lens for understanding whether my nervous system was absorbing the work or quietly falling apart.
AI PACER is being designed to give that same awareness to anyone training with intention. The system watches your effort in real time, then uses HRV and trends to shape the next block: less guesswork, less bravado, more smart adaptation.
