How it works

Three steps to your plan

No questionnaires. No generic templates. Pacer uses the data your Garmin already collects to build a program that's genuinely yours.

01
Connect Garmin
Authorize Pacer to read your Garmin Connect data. We pull your activity history, heart rate zones, VO₂max, and training load — securely.
02
AI Analysis
Our model analyzes your fitness baseline, recovery patterns, and race goal. It identifies the right training load, pacing targets, and weekly structure for you specifically.
03
Run your plan
Structured workouts sync directly to your Garmin Connect calendar. Each session includes zone targets and step-by-step guidance on your device.

What makes it different

Built on your biology

Generic training plans ignore the most important variable: you. Pacer starts with your data, not a template.

Heart Rate Zone Training
Every workout is calibrated to your actual HR zones from Garmin, not a generic formula. Easy runs stay easy. Hard sessions are hard for the right reason.
VO₂max-Aware Pacing
Pace targets are calculated from your Garmin VO₂max estimate and recent performance — not last year's race time you entered into a form.
Adaptive Week-to-Week
Pacer re-evaluates your plan each week based on how your body responded. Miss a workout? Hard week at work? The plan adapts around you.
Native Garmin Sync
Workouts appear on your Garmin Connect calendar automatically — with targets, lap structure, and coaching notes. No manual imports.

Training distribution

80/20 Built In

Elite runners spend ~80% of training time in low-intensity zones. Pacer enforces this automatically, so you build aerobic capacity without burning out.
