Apple Watch to COROS: Import Your Workouts Into Training Hub

By Josep Mampel Marques, updated November 11, 2026

You can import Apple Watch workouts into COROS Training Hub as FIT files. COROS's help says to sign in at t.coros.com on a computer, choose Activity List at the top, then Import Data in the top right corner, and select a zip file or individual .fit or .tcx files. COROS's own guide for Apple workouts uses a converter app first. FitMigrate can make the FIT files in your browser from the Apple Health export.zip, with the GPS route and heart rate each workout recorded. We have not been able to test an upload to COROS ourselves, so import a few files first.

What COROS says about importing

• Where: the Training Hub website on a computer. COROS says the phone app does not accept importing activity history.
• Formats: .fit or .tcx, as individual files or in a zip. COROS says files converted from some other type may fail, and recommends data that was originally FIT or TCX.
• Size: COROS lists an import size range of 20 KB to 200 MB.
• Activity types: if the zip contains an unsupported activity mode, the whole upload may fail. COROS widened the list of importable types in January 2026.
• Daily data: steps, heart rate and sleep cannot be imported.
• Time: big uploads can be slow; COROS says to keep the browser open until it finishes.

Step by step

1. Export your Health data on the iPhone: Health, your picture, Export All Health Data. See the exact taps.
2. Open FitMigrate on a computer and choose the export.zip.
3. Click FIT next to one workout to test, or Download all workouts as FIT (zip).
4. Sign in at t.coros.com, open Activity List and click Import Data.
5. Upload one or two FIT files first. If they show up with the right sport, time and route, upload the rest in batches.

Why start with a test

FitMigrate maps Apple's workout types to FIT sports for running, walking, hiking, cycling, swimming, rowing, elliptical, stair climbing, yoga, strength training, HIIT, skiing, snowboarding, golf, tennis, soccer and basketball. Any other Apple type becomes a generic activity. Because COROS may reject a whole zip when it contains a mode it does not support, upload the common sports first and treat the unusual ones as a separate batch. Also, FitMigrate writes one lap per workout, with no splits, running power or cadence.

If you prefer a converter app

COROS's guide for Apple workouts names iPhone converter apps and then has you zip the converted files and upload that zip. HealthFit and RunGap are two such apps on the App Store, with their own prices and terms; check their listings. FitMigrate is free and needs no account, which suits a one-off move. A converter app suits you better if you want ongoing syncing of new workouts.

Duplicates and what does not move

• If a workout already reached COROS through another connected service, importing it again may create a duplicate. We could not verify how COROS treats that.
• Steps, sleep and resting heart rate do not move. Keep them as CSV with the same tool, as described in Apple Health export to CSV.
• Activity rings, awards and other Apple features stay in Apple's apps.

After the import

Open a few imported activities in the Activity List and compare them with the same workouts on your iPhone: date and time, distance, duration and the map. Small differences are normal, since the distance in the FIT file is accumulated from the GPS points, while Apple may show its own total. If something is clearly wrong, such as a missing route for an outdoor run, check the original workout first; Apple only saves a route when location was on during the workout.

Compare with the Garmin route

The method is the same one used for Garmin: FIT files from the export, imported through the website. See upload Apple Watch workouts to Garmin Connect for how those files are made and what they contain.
