Suunto Data Migration & Two-Way Sync: Connect with Garmin, Strava & More

Why Suunto Users Need Cross-Platform Sync

Suunto makes excellent hardware with a refined Suunto App ecosystem. But many users work across multiple platforms:

• Strava: The go-to for cycling and running social. Suunto has built-in Strava sync.
• Garmin Connect: Users who moved from Garmin to Suunto may want to keep their training history and daily activities in Garmin for continuity.
• Intervals.icu / TrainingPeaks: Deep analysis platforms that need full power and heart rate data.

Suunto App has a built-in Strava connection, but doesn't connect to Garmin, Intervals.icu, and other platforms. GarSync, as an authorized Suunto developer partner, fills these gaps.

Three Common Scenarios

Scenario 1: Suunto User Wanting Data in Garmin Connect

Bind your Suunto account in GarSync, create a sync task: Source = Suunto → Target = Garmin Connect. Every Suunto-recorded activity auto-pushes to your Garmin account. Historical activities can also be batch-migrated.

Scenario 2: Switching to Suunto from Another Brand

If you previously used Garmin, COROS, or Polar, GarSync can migrate your entire history to Suunto App. Your new watch starts with a complete training history from day one.

Scenario 3: Suunto + Another Device

Some users run a Suunto watch alongside a Garmin bike computer. GarSync consolidates both data streams into one platform (like Intervals.icu) for unified analysis, with no interference between the two sources.

Setup

1. Add your Suunto account in GarSync's Account Management with one-tap OAuth.
2. Create a sync task: choose Suunto as source or target, select data types (Activities, Routes, etc.).
3. Enable "Sync History" if you want to migrate past activities.

FAQ

Q: Suunto already syncs to Strava. Why would I need GarSync?

A: Suunto's built-in Strava connection is great for Suunto → Strava one-way push. GarSync extends this to cross-brand, multi-platform data flow — Garmin, Intervals.icu, and 35+ others. If you only need Strava, the built-in is enough. If you need more platforms, GarSync is the complement.

Q: What is GarSync's relationship with Suunto?

A: GarSync is an authorized Suunto developer partner. All data sync goes through Suunto's official API, in compliance with developer agreements and privacy standards.

Q: Will migrated activities trigger VO2max and Training Status in Garmin?

A: Yes. Enable FIT device ID rewriting in the Suunto → Garmin sync task settings. This replaces the Suunto device ID with a Garmin device ID in the FIT file, so Garmin Connect treats the activity as Garmin-device-recorded. VO2max, Training Status, and Training Load will update normally. See our Zwift/MyWhoosh sync guide for details on device ID rewriting.
