Every run
has a reason.
Your coach knows it.

An AI running coach built for Garmin athletes - connect your Garmin account, and it reads your training, understands your body, and tells you exactly what to do today. Register to get started.

Your heart rate drifted 8 bpm in the last 5K - that's cardiac drift, not fitness loss. I'd move Thursday's tempo to Saturday.

Only have 30 min today. What should I do?

30 min easy Zone 2. Keeps your aerobic base without adding load. Tomorrow's intervals stay on track.

// How it works

Three steps to your AI running coach

1

Register

Register with your email and confirm it to create your account.

2

Connect your Garmin

Authorize GraviRun through Garmin's official sign-in flow and your activities sync in automatically. No separate app to download.

3

Get coaching that adapts

Share your runs, paces, and how you feel. Get training advice that fits your body and your goals.

// Find the gaps

Your watch records everything. Who's reading it?

Every run generates data. But raw numbers don't tell you why you're stagnating or where you're overreaching. GraviRun reads between the lines - and turns your synced activities into data-backed running reports you can act on.

🔍

Patterns You Miss

Pace decay in the last 10K. Cardiac drift on easy days. Recovery gaps that build up over weeks. The signs are there - you just need someone looking.

📊

Data-Backed Reports

Clear running reports built from your own activity data - effort, pace, heart rate, cadence, and terrain in context - written for experienced runners and coaches, not for dashboards.

⏸️

Pause & Recovery Insights

Where you stopped, how long it took you to settle back into rhythm, and what that says about fatigue - practical pause and recovery insights you can use in your next session.

// Adaptive planning

Life happens.
Your plan adapts.

Slept 5 hours? Traveling? Feeling off? GraviRun adjusts - not just the workout, but the reasoning behind it. Because a plan that doesn't bend will break.

It understands periodization - base phase, build phase, peak, taper - and builds each workout to fit where you are in the cycle.

Slept 5 hours. Should I still do intervals today?

Recovery looks low this week - resting heart rate is up and your easy pace has drifted. I'd move your threshold session to Thursday. Take an easy 5K today instead.

Traveling all week. Only Saturday free.

Got it. If you can fit easy 20-minute runs Tue/Thu - even hotel treadmill counts - that'll maintain your aerobic base. Saturday: 45 min with 2x1K at 5K pace. Not 3 - your legs won't be ready for full volume after a light week.

// Fully customizable

Your goals. Your words.

Tell GraviRun what you want in plain language. It builds the plan around your life, your injury history, and your watch - not a template.

Marathon

"I'm training for a sub-3 marathon. Focus on threshold pace and marathon-pace long runs, but keep my easy days truly easy."

Comeback

"Build me back from a calf strain. No speed work for 3 weeks - just easy aerobic base and stride drills."

5K PR

"5K PR in 8 weeks. Current VDOT is ~48. I run 4×/week, 40km total. I want to push my interval pace but not get hurt."

// Integrations
