Training that adapts to your body

RunFitCoach doesn't hand you a template. It reads your body's signals every single day and adjusts your training to match exactly where you are — not where a spreadsheet assumes you should be.

Adaptive Engine

Your body talks. The plan listens.

Most apps give you a fixed plan and expect you to keep up. We take in three live signals — HRV, heart rate, and your own perceived effort — to continuously calibrate every session before you lace up.

How it works

All three signals are weighted against your 14-day trend baseline. The AI looks for divergence — not just today's numbers — to catch cumulative fatigue before it becomes injury.

AI Training Plans

Every plan is generated fresh — not pulled from a library. Tell us your goal race, your current fitness, your injury history, and your available days. The AI structures a complete periodized plan and rebalances it as you go.

Built around your race. Your schedule. Your life.

The FIT Score: your fitness in one number.

A proprietary VDOT-inspired metric that tracks your aerobic fitness on a scale of 20–85. It drives every pace target in your plan and updates automatically after races and workouts — so your training always reflects who you are right now, not who you were six weeks ago.
