How it works

From AI coach to Garmin calendar

No long intake forms. Pacer works like a virtual running coach that already knows your training: it uses the data your Garmin collects to build a plan 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

Running coach logic, powered by your data

Most AI fitness coaches guess from surveys. Pacer starts from real runs and recovery—the same signals a good human coach would ask for, pulled automatically from Garmin.

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.

Questions

Common questions

Straight answers about Pacer, Garmin, pricing, and how we handle your data.

What is Pacer?

Pacer is an AI running coach for Garmin athletes. It connects to Garmin Connect, reads your heart rate zones, VO₂max, training load, and activity history, then builds a personalized running plan. It’s for runners who want coach-level guidance without a generic template.

Can Pacer replace a human running coach?

Pacer is software, not a person. It automates analysis and plan adjustments using your biometric data—similar to how a data-informed coach would program training. Many runners use it alongside occasional human coaching, or when a local running coach isn’t available.

How is Pacer different from other AI fitness coaches?

Most AI fitness apps rely on questionnaires. Pacer is built for runners with Garmin: your zones, fatigue signals, and training load come from Garmin Connect, so the AI coach adapts to how you actually train—not only how you self-report.

Do I need a Garmin device to use Pacer?

Yes. Pacer connects to Garmin Connect to use your activity and biometric data. A compatible Garmin device is required.
